For example, with Evergreen State College - yes, because it's a super-liberal college I'm sure lots of kids smoke marijuana on a regular basis. But if it has everything else that he wants (the flexible, open curriculum; the environmental studies; the laid-back student body) and he doesn't feel pressured to imbibe if he doesn't want to, it still might be a good fit. Maybe he should visit?
I think he'd be less inclined to choose PSU since it's downtown and lacks the immediate natural beauty that beckons him to the PNW.
if he were to go the state college route, I sure hope he would choose one of our 23 state colleges and save some moola!
