I am yet to visit SD. I forgot some additional components in my "best place to live" formula. The place has to offer freedom and opportunities for artists. I am not sure if you can call it liberal or bohemian atmosphere, or that's too cliche. A person should be able to afford to live and be free to pursue "artistic exploration" in his life, or whatever it can be called. Prague and Berlin must be good in this regard, although I've heard Berlin is getting more expensive lately. SF has a good element of what I'm looking for, but I hear housing prices are driving people away. Is SD as active as SF or LA in terms of art exhibitions, museums, clubs, people gatherings?
