Austin seems the obvious choice. Of course it's hotter than hell there, humid, and you probably have to have an eye out for Tornados.

Personally if I had to pick anywhere but the Seattle area (perfect for me, the gloom doesn't effect me like it does others), it'd have to be either SLC or Boulder/Castle Rock (both near Denver).

SF is probably better climate, IMO, and the idea appeals to me, but the cost of living combined with the traffic... no thanks. Seattle traffic is above what I consider acceptable, SF would kill me.
