A number of folks participated in the 2012 Unicycle Tour of San Francisco, a 41-mile odyssey through most of the major tourist spots in SF. Ricardo got a bunch of helmet cam photos and videos:
We went over to Golden Gate Park for a little bit of exploration on 29ers, and some disc golf. The disc golf turned out to be a bust (note to self: that course is ridiculously busy on decent weekends, get there early AM or forget about it), but the exploring was cool, found a few lengthy flowy sections for big wheels. It was nice all the way out to Ocean Beach, which is a rarity.
