I like all the suggestions especially the ones about the part from the car that fell off or shooting out her tires. This coming from someone in another Land of Rednecks.
I would try talking to the police. If I understand it the lane is on your property? So they need to abide by your rules? Correct?
If all else fails, talk to the nice boyfriend and ask him what the heck he sees in a 2 toothed redneck??
