This is what Mr. Fix-it and I did this weekend. I was a little nervous getting started on the Segway, but after I got used to it, it was great fun. We had to stay below 6 MPH for a bit, then got to speed up to 10 MPH. Here we're going down a slope which was also fun. The machine doesn't let you go over the top speed and in fact it "pushes" against you when you approach it, which is a little disconcerting. All in all, quite fun and I wouldn't mind having one myself, though I'm not sure where I would ride it.
