[pct-l] Which book?

[hungry10 at hotmail.com (Maury Schwenkler)]

Greetings to all. I have been lurking on the list for a while, busy planning 
to start the PCT in April. I think only one of my major questions has never 
been addressed here--what information do the various guidebooks have and 
what is 'essential' to bring?

I'm referring to the PCTA guidebooks, the data book, and Yogi's handbook (am 
I missing any?). I have a good idea of what's in Yogi's book from the sample 
pages. Can anyone describe what the others are like so I don't have to buy 
them to find out? Any comparisons to the AT data book, Companion, and 
Wingfoot?

I really only want my book to tell me about Water, Resupply, and not getting 
Lost. Everything else detracts from the adventure.

Also looking for advice concerning maps.

Thanks, and see you in April,
Maurice Schwenkler
