@dyslexia,
It is a three day trip, the first day is class 3, 2nd day is class 3 in morning and rock climbing and rappeling in the afternoon and the 3rd day is class 4 and 5 (the Gauntlet) looking forward to it. My only paddling experience is countless hours on a canoe in the BWCA, this should be a bit more intense.
After the rafting is another first, fly fishing. My Aunt has a spot picked and the gear. hope the learning curve isn't too high.
