20-40K? Get real. Do the math.
Won't mention the Baldwin giudes name, he told me his chit (which he bought from someone else) cost him 20k. I could not get one from the USFS etc. This is the permit that allows you to guide on the PM.
As far as fishing gravel goes, why would a sportsman fish anywhere near bedding fish? Bedding fish make poor angling targets, day or night. Good fishermen leave gravel alone and lead others by example.
Then there must be a ton of bad fisherman in the PM "holy water" everytime I go I see guys fishing to bedded fish and ignoring the deep dark water behind them. Please do not say they are from out of state, far too many Mi. plates in the parking lot to prove that.
