I'm from San Antonio so I can answer your questions. Well, I live in San Antonio, I was born in LA.
Anyways, SA is a big city with about 1.5 million people. Lots of stuff to do and what not has everything a big city has. Right now it's just getting into the 40s at night sometimes in the 30s Fahrenheit.
And I've never heard that people in SA hate Jewish people. They're all pretty friendly. There's a big JCC near my house.
