Houston Hobby?

Got one? A Houston hobby or two?

So, I'm going to Houston next weekend for the first time. And I'm looking forward to seeing a bit of the world that is new to me.

Since I've never been and since I only have two half-days (not two and a half days), I'd like to solicit recommendations for things that I must do on such a short turn-around. I want to make the most of my brief visit. What would an east coast girl like me enjoy? How should I eat, drink and be merry?

Please, anyone who has spent any time in Houston, send words of advice and tourism my way. I will have access to a car.

Thank you, thank you!
