I saw a show on I think it was OLN on thes two guys that were touring nepal and tibet on mt. unicylces. they were doing crazey free ride drops and they went down this super long stairway/trail/road that went over a pass in the himilayias in a rhodedendron forest at 16,000 feet. The one guy was like "yea you can go more places and do a lot more terrain stuff with a unicyle than you can a mtb"(as the film showed him hopping down a bluff going ledge to ledge like a trials rider) they also taught some tibetian monk how to ride a short distance(none of them had ever seen a unicycle).
