I caught this photo while riding the Max.  He had just unicycled his way up the killer hill on my commute home.  Later, I read an article in the Oregonian about four guys who rode unicycles 100 miles for the annual Reach the Beach ride.  This has to be one of them.
I guess not! I cannot believe that people use unicycles as a viable means for transport – and that these people are not part of a traveling circus. Very interesting! -S
