Beautiful day in a beautiful canyon following a 2.5 hr wait to drop into the canyon itself. There was a guide group of 20 people with about 8 SMALL children (whom they were lowering into the canyon with harnesses that didn't even fit snuggly around their legs) holding up 5 groups behind them at the top of Cassidy Arch. Several groups of canyoneerers came and left when they saw how many people were at the top... Rumor was the group of 2 following them asked if they could go in front of them and were denied saying "We're going to be quick!" I'd rather have to get a permit at that point and have a better day for everyone involved. And kick out the guide groups. Left car at 11:30 am. Dropped into the canyon at 2:30pm. Returned to car at 7pm. Group of 12.
