RE: Landowner thank you gifts
A box of Omaha Steaks. I'm a veterinarian so I always offer to do their fall cattle work for free.
Another avenue, found by accident, trapping beaver and coyote. I like to trap and and am fairly profiicient. Once word got out I had people calling or coming by weekly wanting beavers removed. Ended up taking a bunch off of a property for a fella that doesn't allow anyone to hunt. Was visiting with him one day about bowhunting and he said, "You really helped me out with the beavers and I appreciate it, go ahead and hunt here if you want to." I now offer that to them as well if I notice they are having a problem. It can get you onto a lot of places.
