"There was a guy using a unicycle on the MUP the other day. Slower than walking!"

I don't live in your area, but do ride a unicycle on the MUP around here.

Actually, it's faster than walking, but slower than jogging. This is with a 20" unicycle. People with larger unicycles do get up into bicycle speeds, though. But the point of it is not to get somewhere; I'm just riding in a big circle anyway. The point is fun, exercise, learning, etc.
