I’d say UNICON would be the #1 choice as well, but since it’s every other year, it’d be this year, or 2010.
America
(every year, all but the last)
-This years NAUCC (North American Unicycle Convention and Championships) is the first weekend in July, I think in Gorgia. (ALL Styles)
-There is Moab each year in late spring for trials, street, and MUni.
-CMW (California Muni Weekend) is usually in the late summer in California (Muni, trials). I don’t know this years location.
-Northstar at Tahoe (ride the lifts up and Muni down, probably 10+ riders). No solid date yet, most likely in July (anything other than the second weekend works for me). I’ve made a thread on it, but they haven’t released their offical opening date yet
