this was the first. The organizer was psyched for another one next year, and most of the participants were as well. As fatbike popularity grows, I'm sure there will be more. Tucson's wash system lends itself to this for sure. Needs to be some tweaks which we all agreed on - a gpx track, even though with the 50-100 yard zigzags it wouldnt be totally accurate. Also the bar stops were too close together imo, though some enjoyed that part!
For me, Underground Races are the way to go! But was fun also to see Todd Sadow from Epic Rides one of the eager participants.
