My ol' stomping grounds, although it has been about 8 years since I've been back. It will probably be hot and humid. You might want to stop by the Dixie Chicken, Chicken
Oil Company (although it may have closed), and the Cow Hop where you can get a very good Cow Pie and nachos. Texas A&M is huge and the Bush library is on campus, although I have never been there. Houston - even hotter and more humid - and Austin are both about 90 miles away. Hope your trip goes well.
Regards.
