Houston... we have a problem

In Texas we visited my relatives' house in Houston, so what is Houston famous for? The Johnson Space Center of course. We took a tour of where the astronauts actually train. We watched an Imax thingie, a performance about how to live in space, rode a tram car around the cite, and did bunches of touristy stuff. Michelle and I tried on the alien glasses in the gift shop, as you can see.
