I also find that older (70+) are more inclined to let you hunt than younger. They don't hunt themselves, they have old fashion notions about letting others use their property (actually letting them) and their children usually are older and don't hunt or are out of town. I got permission last year to hunt a farm behind where I work. I started out by asking her if I could walk her farm during my lunch hour for excersise. Later I told her I saw lots of deer sign and asked her if she allowed people to hunt. She let's me and my father hunt. A nice Christmas card or little gift (ham, jellies) helps solidify relations as well.
