Had some friend who went down at .9 , don't know that they would do it again. The first several miles are pretty bony, dry, dusty and all that.
Shearer is about 10 miles down and is a great strip and camp. Moose is the hell on top of that hill. To carry down some kayaks wouldn't be bad, but to carry down several rafts might be a challenge.
Bring a fly rod. Fishing should be spectacular.
