We have a couple unusual bicyclists but the most unusual is the mostly naked bicyclist. Every day at 4:30 he's either out on Apalachee Pkwy. or LaFayette St. in Tallahassee, FL, hauling it on his bike with krate style handlebars. The bicycle seat is way up so it looks like he's standing. All he wears is a little Speedo. He'll never be hit by a car because he's highly visible. Actually, I'm surprised he hasn't caused auto accidents from people looking. Check out an image at the bottom of Joe's Bicycle Shop home page http://www.joesbikeshop.net/ - scroll way down.
There is also a sometimes homeless artist who rides a tandem hand-painted vintage bike. The bicycle basket is made of macrame with wood limbs that are bent for support. The wheels are decorated with yarn to look like a dream catcher. The bike looks almost organic. I really like it.
