It's really pretty for scenery and everything. Just learn how to duck and cover when that massive earthquake hits, whenever that might be. I rank California cities as SD, SF, LA.
I went there 2 years ago and surprisingly the field looked really good, but the area is disgusting and sucks any bit of life out of you if you're in the Bay area.
I blew my knee out 10 years ago and when it is really cold out it still hurts, also after a long day snowboarding it gets pretty bummed out too, feel for Travis here.
