I believe adults fishing with youth, 14 and under, should get a break on the price. One adult and one youth is only charged for a 1 angler trip. One adult and 2 youths, or 2 adults and one youth are only charged for a 2 angler trip. I do not charge extra for a third angler if 1 or 2 of them are youth. Some of my most memorable days on the river have been fishing with youngsters.
I only take 3 in the raft if 1 or 2 youths are with adult(s).
