In reply to markalmack:
I've wild camped in squamish with a couple of locals - we went a long way down an old logging road and weren't disturbed. It isn't encouraged at all though, and bears are bloody scary, even when they aren't really there...
"stawamus chief provincial park campground" was a nice place to stay, about 10 mins walk from bouldering, single pitch and multi pitch up to 15 pitches ish. Not that cheap, but everyone there was a climber. I got the impression this was the real place to be.
Email me using my profile and i'll scan + email you the accomodation pages from my guidebook.
BTW i am extremely jealous - only spent a few nights there, can't wait to go back.
