After my grandma passed away, she left over 100 acres of land to her kids (my dad, aunts, and uncles, obviously). Of the 5 (of 7) that were left, only 3 actually wanted the land (they live the closest to it). 2 of the 3 live adjacent to the property. 1 of these actually hunts. This uncle has buddies from work that hunt as well, and they've been hunting the land for a few years now.
Both of my uncles that live adjacent to the "family" land heat their homes with wood stoves, so they spend a lot of time cutting and splitting wood. My non-hunting uncle got sick of the buddies using the land and not "paying" to use it, so he decided that if they wanted to hunt, they'd have to do some work on the land; clearing trails, cutting/splitting wood, etc. To level the field, he told me that I'd need to do the same in order to hunt, and to keep the whining of the buddies to a minimum. I didn't have a single problem with this, though I haven't done any work there yet (I haven't hunted the land in a couple years).
I also hunt on land owned by an uncle on my mom's side of the family. I've repeatedly asked him if he wants me to do anything for him in return for using his land, and he's told me no. I HAVE, however, "paid" him with deer livers.
On a similar note, I use my wife's cousin's set up for processing my deer, and I use the deer heart to "pay" for those services.
In short, I'm more than willing to do my part in order to use someone else's land that they pay for and maintain. It's a small price to pay for doing something I enjoy doing.
