I'm a neighbor to one of the fields they lease. The tractor drivers do not hesitate to drive up into my land in order to turn into the field. It makes the ground bumpy and painful for me to mow on my riding mower. I'm sorely tempted to lay spikes that will destroy tractor tires. When I tried to flag down the driver to ask him to stay off my land, he waved at me, like he was in a god-damn parade. PLEASE be more considerate!
