I don't know why, but I really like escalators. I always have. Here's a picture of one of my favorite escalators. It's in the subway station at Porter Square and it's HUGE. If I weren't with a group of people, I would have played on this for quite a while.
I also really like water fountains... the decorative kind, not the drinking kind (well, I guess those are nice too). Someday, I would love to see a waterfall down an escalator going up! Some may say it's like ice cream on pizza, sometimes two great things don't mix, but I would argue that in this case... they can!!!
