Old Stone Church

For 9 years we have lived next to OSC. Our new house and land was surveyed yet when we moved in we found the congregation routinely w/o asking, parked all over our large front lawn to the point we could often not get out of our driveway-even Easter Sunday. Tho they had a parking lot, they refused to use it. We asked them nicely to park on their own land. They nastily refused. We paid $5,000 to them to pave their parking lot. We were never thanked. Soon after, the church started a garbage dump of filled garbage bags, rusted furniture and trashed lawnmowers and sharp junked metal. The worst is a trashed, rusted 1950s? Trailer, so big and high a fence wouldn't hide it. Once again when asked nicely to clean up a hazardous garbage dump, they refused.
Now, we need to sell our home and no one will even go in our house to see it because of the church's garbage dump.
Once again they ignore our pleas to clean up the dump on our property line. They own five acres--tax free! Please help.
