sunny, what's wrong with Davis?
I've been there a few times and it seems nice if you like the environmentalist, small town college feel..
Natural power buses, lots of shade trees and parks, cheap all you can eat chinese restaurants (yum!), some smart people..
I've had friends of the family who attended or taught at Davis and liked it.
Not to mention, it's used to a bicycle town, and so still has a lot of bikes, bike lanes, is bike friendly, etc.
It's one of the few towns I've been to where most of the drivers seemed sane and considerate of each other too. =)
I imagine living there could be a whole 'nother story, but what didn't you like?
