Four wheeler riders better stay out of my yard. I only have two acres. My garden is right next to the white wooden fence that surrounds the barn yard (my driveway turnaround) for the barn that belongs to my next door neighbors. My neighbors own five acres in the middle of a twenty-five acre farm (owned by the wife's step father) and their land is unfenced.
That's hard on us four wheeler riders.
The Nazis used to stretch piano wire across the road and it'd take off one's head when riding in a jeep. They used to place a vertical blade on the front of jeeps and they'd here the wires twang as they drove down the road.
