I'm mostly just venting, but the context here is: A couple times a month I will use my moms large backyard located outside city limits (Thetford Township, north of Flint) for target practice. She lives on 2 acres of land with cornfields stretching for another mile behind that. She loves shooting with me occasionally and we either load up my .357 snubnose with .38 special and shoot soda cans, or load my 20-gauge with birdshot and shoot at clay pigeons. Always safely and always well before 7pm.
We've been doing this without issue for nearly 10 years, and my grandfather (who built the house in the 60s) had used the property to shoot with his kids and grandchildren for nearly 50 years before that.
But the neighbor who just moved in next door doesn't like it and even if we shoot for 20 minutes, the cops always show up in the driveway. They've spoken with us and basically said "We can't stop you from shooting on your property, but we can't stop him from calling us either, and we have to make contact anytime we get a call." Then occasionally when they leave after telling him "we can't stop them from shooting on their property" he will turn his subwoofers up to 11 and blast music until 10pm (which he NEVER does otherwise). A couple weeks ago he even walked across the backyard in the middle of the night and planted a "NO HUNTING" sign at the back of her property mounted on the side of an old mailbox. The cops told him not to trespass again. (Also, neither of us hunt)
What would you guys do in this situation? Just continue on as usual and talk to the cops anytime you want to plink for a half hour? We do plan to continue shooting. However I'm worried that the neighbor might eventually try to do something extreme and file an injunction and take us to court, and I don't need my mom having to go through a lawsuit, even if its frivolous.
