Last week we went up to the top of the Arch. You go underground to get on the tram and there are some little shops and museums/videos to see. You would never know that all that was underground. The little tram you ride on looks kinda futuristic. It's got these 5 seats in a circle and you are touching knees with the people next to you. I get claustrophobic sometimes, but this wasn't as bad as i thought it would be. Once you get to the top there are windows on both sides but you have to lean over to look out.
Here is a picture i found online from I'm guessing the late 60's or 70's (the arch was built in the 60's). On the left is in the tram and on the right is looking out the windows. Clickhere to see picture.
