Hey Jon!
Unfortunately Pritchett is not on the list of event runs this year so it would have to be a pre-event run. There are two new trails, one is more a sightseeing trail that is a little bit out of town and the other is The Pickle. I'm pretty sure Behind the Rocks is the most technical trail on the event list. Also, added last year and totally worth the effort is a wednesday night run. This year it is on Hell's Revenge, last year was Fins and Things.
I'm bummed to hear that as a group you are holding off another year but I can't blame you. If I was still in NC my rig would not be ready for the journey. Johnny C is also not ready for this event as well as any NC folks. I'll hold out for you guys all to come next year. But, if anyone decides to make the trip this year I currently have two bunk beds open in a cabin at Slickrock. I offered it to the NC boys first but no takers. $130 each bed for the week Sunday night through Saturday night.
