Having worked a few private lands WEST of the Mississippi there seems to be some common concerns among land owners. So put yourself in their shoes when asking permission to use their land and remember this, it only takes one person to do something stupid and it's game over for everyone.
Here are some of the minor things that land owners have said to me, " Just make sure you close the gate when you come in and out ", "Don't tare up my gravel road by racing up and down it ", " No shooting guns ", " Stay away from or keep out of this area ", " don't leave any trash or make a mess ". Some don't allow drinking, while others offer you a drink. Sometimes the land owner will ask for help doing something and that's a fair exchange.
The major concerns have been fear of me accidentally starting a fire or I get hurt and sue them. Now I am just one person, so multiply that fear by 100 people coming on to their land and you can understand them being reluctant to give permission to a group or club. So what safe guards can we put in place to give the land owner peace of mind and / or whats in it for the land owner to make it win win for all ? There are of course other concerns that land owners have and I just put forth some of the more common ones off the top of my head.
I do know that respect for the land owner's property opens doors. For example I was doing some metal detecting and this guy drives up, stops and starts talking to me. He tells me that he owns a farm down the road and that there was a tavern on property that burnt down in the 50s and then asks, would you like to run your machine over the area ? I said YES and he said show up tomorrow morning. The next day he shows me where the tavern use to be and I went to work. At the end of the day I knocked on his door, showed him what I found and told him to pick the find he liked best. He tells me that's okay, you can keep everything and then he walks over to where I detected and looked around. I had left no holes and no trash laying around. He then says come back tomorrow and he would show me where the old homestead stood. I believe that I had been tested and he saved the best for last. Ron
