Dont get me wrong, I understand the draw for LA in many areas, and the fact that there is skiing? that's cool. Hell, I have a film/media studies degree and now i'm going for my MFA... going to LA wouldn't necessarily be a bad thing in my field.
However... if I'm going to college, but want really legit ski options nearby? I wouldnt be anywhere near LA, because manmade snow and gaper crowds at High and Bear just doesnt cut it for me. Maybe that's just a personal thing, but so be the case. (It's the same reason why if I was near Tahoe, I wouldnt be getting a pass at northstar or boreal, and instead would be at alpine or squaw... which both have legit parks, less crowds AND better mountains/snow - and why many SoCal people get mammoth/june passes)
I do see your point as far as programs are concearned... but also, take into consideration that getting into high end programs at UCLA and USC and a lot of those schools are much harder for somebody who is coming from out of state. (UCLA's film program takes 80 students a year. Long Beach's takes 200 [if i'm not mistaken]. In-state students get priority. Competitive much? Personally, I dont like such competition. doesnt make things practical enough.)
By the way. There is no UCLB... There is a UCSB, and a CSULB, but no UCLB lol.
