well i didn't read through all of this thread, but i'll put some input in.
me living in texas all my life, i was born way way south, like 10 minutes from mexico, moved to houston when i was like 6 and been here ever since(now 19). i have family all over texas but my closest relatives are in san antonio. i visit there atleast 4 times a year and i may even end up moving there in the near future, like within a year, probably next spring semester to attend utsa.
but anyway, san antonio is a great city. but like most of texas(southern atleast) it is very diversified. although i've never been upnorth, i would guess there are majorites amongst the population(whites predominantly i presume?). i like the fact that texas has such a mixture of people, especialy in the big cities like houston/austin/sa/dallas.
i guess theres' alot of things to do here, like fishing, go to the beach, and water/amusement parks. but i think that's anywhere you go except for maybe the beach. san antonio is a beuatiful city though. ummm idk what else to add, so i guess just ask if you've got any more quesitons?
