Yes I thought of that, I thought I'd post a few signs saying "enter with vehicals at your own risk, you will be proscuted". If they are smart enough to read it, then they might think twice, but they have been forwarned. I might put another sign by the rule board stating the deterences are in the tall grass outside the walkway area, or I could just put up a snow fence with the pipes, they might think the pipes are a joke, but when in the ground 3-4 feet and only 3 feet above the ground, it makes a great vehical catcher when they hit the soft ground and ride harder on the bent pipe, if they try to back up, hook line and sinker done.
