Attended "Operation: Ouray" weekend trip last year as a volunteer to help guide the group. It was a great time all around. Intro camping, canyoneering, hiking and standup paddle board. We also toured and learned about Box Canon and Black Canyon of the Gunnison. Very packed and thought out itinerary and I got to meet a lot of great people (some of whom I am still in contact with). Would highly recommend participating in one of NNDT events either as a participant or as a volunteer!
