I will say that if your current location is Minnesota, you might not like it.

I agree with Tony, Jeff. I've been to Houston, San Antonio and other parts of Texas and it doesn't seem like it would be a huge adjustment if you like Houston and Texas in general. I actually spent 6 months in San Antonio many years ago (at Fort Sam). I have to say that compared to the freezing winter hills of Fort Knox, Kentucky, we all thought we had died and gone to heaven!

San Antonio is pretty big, spread-out, with lots of miltary and bases. Once you've seen the underwhelming Alamo, you may have exhausted the list of historic attractions, but downtown has some interest - canals/riverwalk, restaurants (yes, the best Mexican food I rememeber ever having on this side of the border) and clubs.

If the opportunity seems like a good one (and depending on your estimate of prospects in Houston), I'd give it a shot.
