Santa Cruz? Have you been there? It's definitely a love it or hate it kind of place. The food is better in SF. It's something like 78 miles down the coast, so the beer and wine are the same. The landscape is about the same. The big problem is going to be your commute over hwy 17. I did it for years and liked it, but it's not for the faint of heart or the skittish in car. Never been to Raleigh or Austin, but today was high 60's low 70's, and went for a walk on the beach. The weather will likely be the same in the dog days of summer. Can you say the same of the south/texas?
As for San Francisco not wanting people. It is over blown in my opinion. San Francisco did not want the gays, hippies, beats, Hispanics (even the one's who were originally living here), Chinese, Japanese or any other group who moved in to the city. Never stopped anyone and everyone gets over it eventually...
