We went to Houston last Fall to see Body Worlds @ the Houston Museum of Natural Science. We visited the museum that day, but had to call and get on a list to see the Body Worlds exhibit at 1:45 in the morning.
We went to the zoo the next day with my parents and nephews. I took a few pictures, but not many.
Oh, and at some point we rode the train.
We need one of those things here.
