The best part about the Science Center (other than the fact that it's free!) is that you can see the space shuttle Endeavor. It was very cool to think about the fact that this thing has actually been in outer space. I knew it would be big, but when you see it in person you can really see how huge it is. I was wishing for my fish eye lens during this part since my standard 50mm lens couldn't really show the scale of it.
