I think you might be surprised as to how many people you will encounter on a thru-hike that bring mini-music players along.

Really?  I can understand carrying a cell phone and GPS, but headphones/music?  It's just my opinion, truly to each their own, but I've never seen anyone walking the trails with an earbud in.  I live in Minneapolis, where thousands of people zone out to their iPods while walking around the lake/strolling by the Mississippi, etc...but this is a city, and I still find these people confusing.  Isn't the reward of being outside...being outside?  To those who must have the headphones, I'm sure you're wonderful people, and I'm sure I'd drink a beer with you...or maybe I wouldn't.

  White Wolf Lodge generally has minimal supplies at its store--the 
 variety would be more comparable to what you'd find at Glen Aulin and 
 the other High Sierra Camps than the Tuolumne Meadows store.  My guess 
 is you'd be able to purchase various candies, batteries, and maybe a few 
 freeze-dried or canned items.  There is also a small restaurant where 
 you could get dinner or breakfast.  A daily hikers bus that travels 
 between Yosemite Valley and Tuolumne Meadows stops at White Wolf.

Check out this headlamp: 
ww.zebralight.com/H30-Q5-Headlamp-CR123-Flood_p_9.html 
Durable, simple, adjustable output, lightweight(2.2oz with battery and 
eadband), very bright and efficient Cree LED, and the lithium cells are 
ery lightweight and long-lasting. If you want one, order it NOW, since 
hipping from china takes 2-6 weeks. 
he batteries are very cheap if you buy them here: 
ww.batteryjunction.com/tpen-tcr123a-.html (apparently the business is 
emporarily suspended due to a fire, but they should be accepting orders 
gain soon). 
An even lighter option would be a photon light, and use the included clip to 
ttach it to your backpack, hat, or bandanna: 
ww.photonlight.com/Photon-Freedom-Micro-Keychain-LED-Flashlights-p/fm-led-keychain-flashlight.htm 
goog_1268831470430> The cells last a really long time unless you turn 
t on accidentally. You 
an find the CR2016 coin cells for the photon light on ebay.

  little history - when this product first came out, it WAS called an ice 
xe. There was so much flack thrown about on the web by both backpackers and 
limbers. I'm sure that had a lot to do with changing the name. It's no 
onger an "ice axe", it's a "potty trowel." Some of us have no qualms using 
his "potty trowel" for other purposes. 

I agree that if you want to use it, you should use it.  Carry whatever you 
ant, or don't carry any self-arrest tool at all.  Safe is a relative term 
nd we each make our own choices. 
However, Adam's question was, "is it strong enough to self-arrest"?  The 
nly correct answer is, "It has not passed the standard CE B test so it is 
ot rated for self-arrest."  The ice axe standards are the way they are for 
 reason - mostly because the mountaineering community has a lot of 
ollective experience with ice axes that fail and the consequences that 
ollow.  The ULA Potty Trowel doesn't meet those standards. 
Now, you might reasonably think that the typical usage on a PCT thru-hike 
on't stress the tool to the same degree as typically mountaineering, so the 
otty Trowel is ok.  That's a reasonable position to take.  Though I think 
ed has a good point too - if you're confident that you're not going to be 
n a situation where you'll put a lot of stress on your self-arrest tool, 
hen are you really sure you need to carry a self-arrest tool? 
HYOH and all that.  But Adam needs to understand his choices.

For those considering packer resupply along the PCT/JMT in the Sierra, I just 
eceived this information from Dee Berner of Sequoia King Pack Trains: 
NOTE - neither web site is up right now. They should be available within 3 
eeks. Until then, use either email address or call direct toll-free. 

he email addresses are correct, bernerspack at yahoo.com or pinecreekps at aol.com, 
nd phone is 800-962-0775.  Dee is offering discounts for July and September, or 
ith folks who can pair up on the same days (they usually contact her and she 
an figure out what's going where).  They do resupply service from Taboose area 
own to Tyndall areas (including Wright Creek).  As I noted last month, the 
east expensive is Kearsarge Pass areas. 

or resupply service at Kearsarge Pass and Charlotte Lake areas, the revised 
ebsite will be  www.sequoiakingspacktrains.com 

or resupply service at Franklin Montgomery Mdw, Evolution Valley areas, or 
oneymoon Lake for those folks up around Bear Lakes Basin, our website for Pine 
reek Pack Station is www.pinecreekpackstation.com

Thanks for the tip on the shorter cable, I just ordered one.  I have had good 
esults with my iPod Touch (just like the iPhone in most ways but without the 
onthly phone charges)  using  the Solio classic solar charger, which also 
erves as a storage battery when charged up via the wall plug.  I get two 
harges of the iPod Touch with it.  You can also use the sun to recharge the 
nit if you hike in those conditions.  The numbers are :  1650Amh, 5-6V , 800 mA 
utput range,  4.8 watts. There is also a special adapter you need to buy from 
olio that mates between the Ipod Touch or iPhone and the plug coming out of the 
olio unit.

 I didn't write the following for PCT hiking, but it might prove useful: 
  
 I started with a short cable because it seemed silly to carry a long   
 cable with me all the time.  Because of the case I use, "cableless"   
 options (built-in connector) are not an option.  Also, many of those   
 are rigid or have a case for the phone.  I like my case and making my   
 phone 2-3 inches longer makes the connector in the phone the break   
 point if it flexes! 
  
 ProCable Shortz  in 7cm (2.5") or 20cm (7.5"), a few different places   
 carry them, this is an example: 
 http://www.radtech.us/Products/CablesiPod.aspx#ProCableShortz 
  
 I have the 7cm, and a retractable USB extension (that I bought at   
 Fry's).  I bought the short cable from Radtech, but other places carry   
 them.  They are a good company with great support. 
  
 For batteries, that's more complicated.  Many battery suppliers don't   
 publish the capacity of their battery packs and some that do (Lenmar)   
 overstate them drastically.  Many wish to say crap like "recharge your   
 device 3-4 times" - WHICH device?  My old iPod, my BlackBerry, my   
 iPhone 3Gs?  Others are even worse with "adds 27 hours of talk time!"   
 WTF does that mean?  "My iPod Touch has 0 hours so far, so now it has   
 27?" 
  
 So I deal in "mAh".  That says, if you're not into battery juice,   
 "this battery will put out the stated voltage (in this case, USB spec,   
 which is 5-5.5V) at so many milliamps for one hour or 1 milliamp for   
 so many hours and anywhere in between. So, an iPhone 3Gs battery is   
 3.7V and 1220mhA.  Simplistically, we'll call that 4514VmAh as the   
 capacity of the battery.  In a perfect world, you'd need a charger   
 battery that put out that much energy to fill it back up, but you will   
 actually need more.  There is loss and power used to drive the   
 circuitry to charge the battery and change the voltage inside the   
 battery pack from what ever it is to 5V for USB output.  Since USB   
 output is 5V, a battery pack of 903mAh is one charge of the iPhone   
 3Gs.  Let's round to 1000mAh of USB power for a full charge. 
  
 The other item to be on the lookout for is the rated output power in   
 milliamps (mA) or amps (A).  USB port output for running attached   
 devices is about 500mA at 5V (so 2500VmAh).  If a device like the   
 iPhone 3Gs needs 4514VmAh to fully charge, then at 5V and 500mA, it   
 will need about 1.8 hours to charge - about 2 hours with loss, etc.   
 Some chargers are offering 1000mA (also called 1A, or high output)   
 charging ports for devices that can use the extra juice.  I believe   
 that older iPods (and maybe the original iPhones) are limited to   
 drawing 500-ish mA from the port.  The iPhone 3Gs will do a "fast   
 charge" if it detects a "high output" port. 
  
 I have a Lenmar battery pack that claims to be 750mAh, it makes about   
 30% charge of the iPhone. 
 http://www.radioshack.com/product/index.jsp?productId=3184995  nowhere   
 NEAR 750mAh, but I got a couple at Fry's on sale for less than $10.   
 Very small and can carry in my pocket with my short cable for an   
 emergency.  (No high output port, I can use the iPhone faster than it   
 can charge it; in some situations.) 
  
 I bought this one for Helen as a bigger battery. 
 http://www.radioshack.com/product/index.jsp?productId=3912660   It   
 claims 2100mAh and should be able to charge the iPhone 3Gs twice!  Not   
 so, once and some change.  I bought it at Fry's and didn't get such a   
 good deal.  Both of the Lenmars came with Apple cables, don't use   
 them, they won't work with the iPhone or some later model iPods.   
 Apple changed the spec of their cables...  (Again, no high output port.) 
  
 My current favorite battery is making me frustrated.  It's the   
 Duracell "Instant USB Charger". 
 http://www.duracell.com/en-US/product/instant-usb-charger.jspx  I   
 bought it at WalMart for $20, on a whim, and it's turned out to be my   
 "pocket favorite".  It's very flat, so it's good for the pocket.  At   
 $20, it was a bargain!  It advertises 1120mAh and DOES do a "flat to   
 full" charge of my iPhone 3Gs.  Ever since, when I see them - they are   
 $30 - not as much of a bargain.  Some of the things I DO like about   
 it, it comes with a very short (portable) power/recharge USB cable AND   
 is has an actual ON/OFF switch.  Most of these types of devices do   
 NOT, and as such are always powering the power conversion circuit and   
 slowly draining.  Very slowly, but draining just the same.  Also, it   
 seems that it does put out more than the minimum for a faster charge.   
 This one is so small and flat that I might consider hiking with more   
 than one and call it "done", but then I start getting cheap... 
  
 Then there's BIG juice.  This would be for something like the bus ride   
 to camp and back.  Usually, I'd be in a car with a 12V->USB adapter.   
 I wasn't on the charter to Joshua Tree so I don't know if there was   
 any power on the bus for devices, so do have that. But I go looking   
 and I did order something.  I can't vouch for it's performance yet. 
  
 I considered looking for the larger Duracell.  The Powerhouse Charger: 
 http://www.duracell.com/en-US/product/powerhouse-usb-charger.jspx  but   
 at 2000mAh, it would be two charges at best and was not that   
 compelling, unless I could find it deeply discounted.  I could not. 
  
 I considered something VERY expensive, but with other uses for after   
 Snow Camp, and of very high quality: 
 http://www.hypershop.com/HyperMac-External-MacBook-Battery-100Wh-p/mbp-100.htm 
>  but just couldn't bring myself to cough up the bucks (still, it   
 would charge the iPhone over 50 times! ;-) Definitely a 1A, high   
 output, power port.  I could power my laptop on some car/plane trips   
 and power my iPhone as well. 
  
 The same company has a device meant more for iPhone/iPod use, and I   
 considered it as well: 
 http://www.hypershop.com/product-p/hm36-black.htm still pricey for   
 3600mAh (about 3.5 full charges) but very good quality and probaby IS   
 3600mAh!  Definitely has a 1A, high output power port. (May still get   
 something from these guys, if I get a bonus at work or something!) 
  
 What I ended up ordering was: 
 http://www.imaxpower.com/IMP500-3G-3Gs-iPhone-iTouch-external-battery-p/imp500.htm 
 I liked that it came with a "wall wart" charger that I use for it or   
 for my iPhone or iPod Touch.  I doubt that the cable will work for   
 either.  I purchased it through Amazon, last night, and it shipped   
 this morning.  I'll let you know how it does when I get it.  The   
 online reviews have said 4+ full recharges of iPhones and a charge   
 rate that implies a high output port and a 3rd party doc "confirms"   
 it.  I verified with the vendor that the capacity is 5000mAh at 5V, so 4   
 full charges should be expected with some power left over.  At 130g,   
 this might be "trailable" at about 1oz per iPhone charge. 
 Reviews:  http://forums.macrumors.com/showthread.php?t=565215 and 
  
 I was going to get http://www.imaxpower.com/product-p/imp880.htm to   
 share (with GF), but then what happens to is after the trip is over?   
 This device probably has a high output port, but now I'm not so sure...

Fully charges an ipod twice, has two usb female ports.  When in town you can 
harge 2 devices and the internal battery at once.  You can carry an 
ptional extra batter if you are using a lot of power.  Carried it 2000 
iles, works great and you can't beat the price.
