Have you checked the FAA's website to see whether there are other airports within five miles of your field? Until I checked, I would have bet that there were only two airports in the county where I live. There are thirteen. And, in a way, it is "accidental" that you have a good relationship with your airport. All it takes is one unreasonable owner, or an owner who doesn't want to be bothered with being pestered with notifications, and you're done.
