Sounds like the neighbors from hell. Even though you are outside the city limits and the local police will not respond you should contact the Sheriff in your county and file a complaint. That office should be able to help you. I see you've called the sheriff before; if this hasn;t worked try getting a civil protective order limiting what these people can do. You should be able to get one from your county court. then whenever the sheriff is called show him the PO. That should work.
