I have to tell you, it would be wrong, I see this point from two different perspectives.
1. If you guide this is his way of supporting his family, and although it is on state land he still has to support them.Now speaking of my buddy who is a guide, all state land is his and if he has clients down no one should hunt the area his clients are in, even though we used to hunt those same areas before he became a guide and is all public lands.
2. It is public land and my suggestion if you know how to hunt, do some research on the area via local biologists, sportsman stores, and ranchers and farmers, they will point you in the right direction, and bypass the outfitter all together, to avoid any conflict.
