I wasn't sure I wanted to go up in the arch, but as soon as I got here, I walked over, went down into the visitor center and knew I was going to do it. You're in a little pod with 4 other people for the climb up. It wasn't as bad as I thought it would be, then you get to the top and you can feel it move a little. It made me a bit dizzy, actually, but hey, I've been to the top of the arch!
