If you want to go to a mall, there's the Galleria in Houston. They have an ice skating rink...we were to the one in Dallas before, and it's just neat to go there and watch them skate. BTW, the ice rink in the Galleria is the one where Tara Lipinski trained at.
My mom said the Museum of Natural Science has some interesting exhibits, including a Butterfly garden...it costs something like $5 to get in.
There's also Sam Houston Park, which has 7 historic homes, Bayou Bend Collection and Gardens, Tunnels underground which connect 55 buildings, an Underground Mall (I think I'll have to visit that sometime...sounds interesting! *L*), Water Wall (man-made waterfall), and quite a few other things that probably wouldn't be too hard on the wallet. Here's a list for when you can get back online: Houston Attractions
You might want to skip Moody Gardens, since money is tight...not sure what the cost is of that is now. I know there's also some kind of attraction that has a train you can ride..it's probably more of a kids attraction, but it might be neat to see. I know Cathy knows where it's at, because she told Becky.
The house with the cherubs on the walls/ceilings is called Bishop's Palace. And more things to do in Houston
