I don't know anything about San Antonio but I interviewed at Galveston and thought it was nice. Good faculty and everyone seemed pretty friendly. I almost felt bad about not ranking them higher but I wanted to get a more robust experience with consults than what they had available. Also, I'll admit that I was a little apprehensive about living in an area with a hurricane risk. That being said, the call is pretty light there, which is attractive in its own kind of way.
