Headed out to Moab in a few weeks for the Jeep Safari. Plan on getting a few days of riding in while I'm there. Last time I went, '07, I stopped in one of the bike shops to top off my tires and grab a map. I was riding some super light weight racing tires at the time and the shop guy told me I'd be lucky if they survived the terrain. Will I be in the same boat with the Husker Du's.
