[pct-l] Biggest Difference between AT Thru-Hike

I'm looking for some wisdom on what the biggest differences are between an AT 
Thru-hike and a PCT Thru-hike from some experienced hikers.  I've read 
everything I can get my hands on but if I read it in an email it would help 
drive the point home.  

A few points to start with:

Is the "community" that much smaller?, I know there's fewer PCT hikers but 
since the weather window is so much smaller it would seem everybody would 
still be pretty concentrated.

National Park bears are much more agressive in the west?

Is everybody really focused on their schedule?  On the AT I didn't pay much 
attention because I allowed myself 7 months.  Obviously the PCT requires a 
faster schedule.

These are just a few areas I've been pondering.  Ready to get some wisdom 
from you folks.  Thanks
