Houston Trip Planning

I was looking at our schedule for Houston and on Monday we have a large amount of time between appointments. We have one free valet parking pass left that we didn't use the first time we went down there. Since we have to be there all day (and parking is expensive!), we thought we would use it Monday. That left us with several hours to kill in the middle, so I started looking around for things to do. I found out that the light rail system runs near there and goes to the museum district, downtown, and a few other areas. So, I started looking to see what museums were there, and we found some that looked quite interesting. Our plan is to valet park, do the mammogram, do a couple of nearby geocaches (couldn't resist because they are RIGHT there), hop on the light rail and ride it to the museum district, tour a couple of museums, eat lunch, and then return for the ultrasound at 1:40. I think the break in the middle will make things a little more fun for us.
