LOL, I usually don't call them "young urchins" when I catch them pulling wheelies on my farm land with their ATVs and dirt bikes.
I had an older friend, she was 70 at the time, who was plagued by ATV's, snowmobilers etc. They ran right over her rock walls into her tree farm. I told her to drive nails at an angle in a board and lodge it on top of her rock walls. The left her alone after that.
