Linkfilter: "MUni stands for Mountain Unicycling. It's also known as Rough Terrain Unicycling, All Terrain Unicycling, or even UMX. Like mountain biking, you don't need a mountain to do it. It's just the act of riding unicycles off road.

MUni has been a sort of revolution in the unicycling community, sparking a tremendous effort to build better, stronger unicycles."

er, yeah... A second wheel would be a start!!
