Middle kid has a couple unicycles -- he's the only one around, and rides often. (And he's pretty good, can jump mount, do 180 jumps, ride up and down stairs, and generally he's a comfortable as on a bike. He has played the Emperor's March on a trombone while riding as well. He insists that he's not practicing for the circus).
