Congrats.
Blinn is right by College Station. So I'm sure there will be plenty of bars and what not.
But it's pretty country in that area. I mean real country. Ranches, horses, cows, etc. The true definition of Texas, supposedly.
You'll have the standard urban stuff, but it will be culture shock from Atl.
Brenham is about 45-1 hr away from Houston, if that much. The major highway for that area is 290. If you take 290E, you'll be coming in on the northwest side of Houston. If you go 290W you'll be heading towards Austin. Which from you will be about 1.5 hr away.
I'm sure u'll be heading to Austin or Houston fairly often.
