All the really good ideas have been taken, darn. There are some pretty good ones too. Unfotunately most of them are illegal, drats.

You hadn't answered the one about the easement, but I would assume that the county forced you into so you really can't pull his use of the road.

I would try talking to your neighboor one more time, just to say that you really did try. I would let him know that if she doesn't slow down that you will talk to a lawyer and see what can be done. It is kind of hard to do that in a nice way, but let him know it is not him and that if she deosn't slow down that you have no other choice. Sometimes just saying that will have an effect. Although from the sound of girlfriend I doubt it. Just be prepared to back it up.

Also if you do talk to a lawyer, I would ask them to do some research into seeing if you could get the police involved. You could also just talk to the police, but I bet they would say that there is nothing that they could do.

I am not sure how good of an idea this is, but try to get the streach that they use declared a county road and impose a speed limit of 5 or 10. Like I said this is probably a bad idea, but he you never know.

Also, god forbid, she does hit an animal, try to get the police to charge her with animal abuse.

Good luck, I hope something can be done.
