I keep track of who hunts. I have CRP, and I don't charge. Seems weird to me, but I divorce the idea of income from bird hunting, I guess I feel like it's more important to give it away, to certain people, most of whom can't afford to pay. On the other hand I have participated in leased ground, or access fees, when I went out of state, so I don't have complaint for those who do. I do know guys who's phone rings of the wall, for deer season, pheasant season, etc. Some lease because they are hopeful that it will decrease the calls, with a "leased sign" on a post, and help with trespassers as well. Some times the fee is related to liability insurance fees, to rectify 'hunting accidents". that may occur! If you have a lot of time and energy involved, a lot of these cost real money, to recover some revenue to offset it doesn't bother me, what ever we gain is much better to everyone, fee hunter, or free agent, who hunts in it or around it!
