Fun to watch, hard for me to do. The last time I rode a bicycle I needed a cortisone shot in my knee. I've been on the back of a motorcycle a couple of times but never driven one. If I tried, I would never do it wearing a fake rabbit head.
The group in the third picture is a club that participates in parades around town. They call themselves the Banana Bike Brigade. Oh, and that's a lollypop stick, not a cigarette, in the mouth of the rider in the last picture.
