For San Antonio, TX residents.............?

I am contemplating a move to San Antonio from Tulsa. What are your likes and dislikes about San Antonio? Are there parts of town you want to avoid when looking for a home? Are some school districts better than others?
Update: Yeah, there's definitely not much to do in ol' Tulsa town. Not to mention the eternal road construction.........
Update 2: **May I just say I'm getting great answers, and I appreciated them all. SA is sounding better and better all the time. I am on SS Disability, so does anyone know anything about subsidized housing in the area? (Not public housing though)
