SW,
Don't have animosities toward the farmer that has let you hunt for 10 years at no expense to you. Before the day of the "Deer hunting Lease", he probably spent 10 to 12 hours a day, 7 days a week trying to make a living out of his property. If you dad has land, he can tell you that it is no easy task.
Most of the land owners here are cattle ranchers, and most have figured out, there is more money in leasing land for hunting, than there ever has been in cattle.
Your farmer freind can probably make more from leasing his land, and not having to do anything to it, than having to work his butt off, and barely break even.
Let's face it, the day of the free ride is pretty much over for most of us, and we would all be better off to recognize, that if we don't get hunting land nailed down on a LONG lease basis with landowners, then our children won't have a good place to hunt when they are ready.
There are farmers and ranchers that want to lease land for hunting so they can control how many people, and who they are, on their land. Those guys probably won't take as much money from you, since they are more interested in controlling their property than the other guys who just want the dollars.
Look around and you will find some land, and when you do, ask for a 10 or 20 year lease agreement with the owner.(and take care of his property like it was your own)
