At least all they are doing is turning around. I had a guy park in my yard once. He wasn't visiting me, he was heading over to the park close to our house that a concert was going on at and couldn't find a parking spot, so he pulled into our yard. I called the police and they came, but wouldn't do anything since the vehicle was on private property, it was my problem. I thanked the officers for coming over and they left.
I went to my garage, got out the SUV, hooked up a tow strap and pulled the vehicle out into the middle of the road. Unhooked the tow strap and parked my SUV back in the garage. I then went and sit on my front porch, watching as traffic trying to figure out what to do. Police showed up, looked over at me, I yelled, I think it is your problem now since it is on public property. I turned around and went inside. They had a tow truck come and get it.
About two hours later I heard commotion in my front yard when the owner showed up looking for his truck. He called the police to report his truck stolen, they showed up and arrested him because he had an outstanding warrant.
The most fun I have had by not going to a concert.
