Depends...... If I have to pay for access, forget it. If the landowner gives permission for access without any "enrichment" then I always remember and send something from Cabelas holiday catalog, usually a smoked turkey or such. Learned a long time ago than unless you know them well enough, booze is not always welcome. Lots of "tea totalers" out there.
The first time I hunted a ranch in Wyoming, paid a trespass fee and did really well hunting. Had a problem on a really tough 4x4 road on the ranch and got stuck. We were digging ourselves out when a couple of the ranch security guys drove up and helped us out of the mud hole. They really didn't have to, but it saved us a lot of time. A couple of nights later they dropped by camp and we invited the to stay for dinner and had a few beers with them. Started a great friendship that has lasted over 20 years. Hunted that ranch for years and was a great situation. When the landowner died and his heirs took over, they leased everything out to an outfitter, but we were invited back. I am sure it was because of out past relationship. Don't hunt the ranch anymore, but still are great friends with the 2 guys we met.
Many years ago I used to have a ranch in California that I hunted quail on. My Dad used to hunt it and it carried over to me. We always made a spring trip or 2 over weekends to help out with chores. Unfortunately the place was sold and subdivided.
I am rambling a bit, but the bottom line is you have to make a judgment on each situation and they all won't be the same. Some ranchers will welcome help and some just won't. Some will appreciate gifts, others just won't care. But I am sure most will appreciate your consideration.
