Kris Holm Mountain Unicycle
If you thought keeping your arse upright on one wheel was challenge enough, let me tell you a little something- there are actual humans out there who not only have accomplished that but have taken it outside the circus tent and into the mountains. That's right- mountain unicyclists. They must be descended from the same cavemen (or cavewomen) who first looked at a rock and had the chutzpah, skill and patience to whittle it into a wheel. Then ride it. A different breed, I tell ya. I sought out the help of Wikipedia to find out what, exactly, differentiates a unicycle from its badass mountain cousin and found this: "unicycles typically lack a gear system, preventing the user from coasting or reaching high speeds. Mountain unicycling usually takes place on specially designed unicycles, which are equipped with strong hubs, large, knobby tires, and rugged frames." Ok. That still won't help me keep my nose out of the gravel. Sigh.
