I am seeing them all over the place, these days! Once, I saw a guy speeding down Topanga Canyon Road from the trail head into the canyon (I was driving, couldn't get a picture without hitting him)! As a departure from my recent rantings ( I am becoming quite the grump), I offer my own unicycle pictures-
This guy was actually part of a huge unicycle pelaton. None of the pictures came out!
The duct tape seat is impressive. As is the jersey. They were both really nice guys.
Don't drink and ride.
