He was fascinated with this exhibit on mummies. Ryan was a bit bored by it, and I was more than a bit creeped out by it (I mean, do I need to see thousand year old male body parts, toenails, hair, and various stages of fetuses??). So Ryan and I went through their special exhibit pretty quickly. Alexander and Carl spent a good deal longer, and Alex was so moved by what he had learned that he even filled out a lengthy comment card at the end.
A big hit for the boys was learning about cowboys and vaqueros, and getting to try on their clothes.
They also have a fun playscape / children's museum of sorts, the HEB Science Treehouse.
The boys had never been inside the Alamo before.
And Mexican worry dolls.
