I just finished a 3 day Canyon Rescue course in Cedar City. I wasn't going to go to the American Canyoneering Association annual Rendezvous in Zion next weekend, but the canyons are a callin' and I'm pumped. I met some awesome people in the course, who will attend.
One of many systems we learned was the "cut and lower." If someone screws up I can cut their rope and lower them on my system. Fun stuff.
