My wife and I are attending a conference in Houston this coming week and will have Thursday until Sunday midday free to explore the area. We will have a rental car. We have no idea as to what to do other than we are not really into the traditional tourist things - wife is not a big fan of museums, loves to see the animals (her favorite thing to do is swim with the manatees). Thoughts/suggestions? Restaurants/shops/just interesting places to see. We really prefer the local places. I wanted to go to the coast but we are open to anything.
