YZeezee, there used to be a group that I believe was called Rocky Mountain Trail Riders Assoc.(RMTRA) or something like that. They used to put on a race or two at PMI. I have never had a chance to attend one, though I have seen some of the course markers that did not get picked up the week following a race. The hardest part about this group, asuming they still exist, is finding out when their events are. I alwasy seemd to find out after the fact.
