Cost of Crop damage from glider landing in farmer's field?

I have landed in 8 farmer's fields over my 18 years of soaring in and around Utah and have always been met by the farmers and their families with great enthusiasm and interest in the beautiful ship from the sky that landed in their field...But not all farmers are always sober or appreciate the lines of a sailplane...

We are uninvited guests who may have just run down some of their crop. I received an interestingly threatening comment on one of my outlanding videos ( http://youtu.be/oJgSL4X6L-Y ) from a farmer who saw the video and started talking about things he would like to do to me if it were his field. It brings up the question of what is the actual monetary loss of crop (let's stick with hay or alfalfa for the Utah region) if a glider lands in their field?

A glider landing in a field will flatten 6 inches (main tire width) by around 300 feet of crop. Let's take wheat in this case. That is 150 square feet of flattened wheat or a 10'x15' area. This does not take into account the damage from walking around the field and retrieving the glider but I am assuming the glider would be walked out of the field by the gate that we landed near. Yes, I cut it too close on this video and should have left more room from the fences. The retrieve was very easy thought.

Have any ideas or tips with dealing with angry farmers who don't see the beauty in soaring? Also, what does the law say about our right to land on their private property? We could either land there or crash there - the glider is coming down either way. Can they legally confiscate our glider? Demand ransom or a landing fee? How do you deal with a ****ed off farmer holding a shotgun?

Thanks for any stories or insights,
