Missouri has that no lawsuit rule also, in efforts to help open up private land to hunting, etc. Two of us gained permission to hunt a farm, and has turned into a fantastic deal, over the years it turned into just the two of us allowed, we are friends with the farmer and his wife.
Some advice, I take things to the farmer. I had scored some cheap off road lights for even cheaper, and the farmer runs around on a golf cart down to his work shed all the time, I took him a set of lights, he loved having them for running 5mph down to his shed at night. I ended up with spare golf cart tires, he always had a flat, gave him the tires, he had them on that cart 20 minutes later. I work on cranes, I've given him rigging stuff that was used, just simple stuff he would use for towing not lifting. I jacked up a house once and had 9 bottle jacks left over, I've given away to friends. I saw the farmer one day, he had had a flat in town, and mentioned his sons had lost the jack for that truck, so you know I gave him a jack, no big deal to me, but just thinking of him and how much fun we have on his property, an occasional gift just tells em you appreciate it - I've offered to fix holes in the road but he never lets me, etc. I've picked up trash and made sure he knew about it in passing. His wife likes to garden, and a place near my house always has bags of free manure sitting out, I took 6 bags down (I was going to use them myself), I asked if she wanted them, they had them spread out in her garden before I left the property, I told her I'd grab some more when I could. Its just getting to know them and returning the favor, they don't really need me driving out there and bothering their quiet, but they put up with me, right?
