I had an odd dream last night. I dreamt I was riding on one of those "Segway" machines, the two-wheeled, gyroscope-controlled contraptions that were supposed to be the invention of the century. I was riding all over the Liberty Science Center, the local science museum, on one. I think I was testing it for them. I remember riding it into an elevator to get to another floor, and I was having a good time on it. Not my typical dream--usually they're much more absurd or revolve around some kind of anxiety I'm experiencing. I can usually figure out the symbolism, too, if I think about it long enough. But with this one, I'm stumped.
