I thought about that, my husband has one of those wildlife cameras that works like a motion detector. We have private property signs up, they just tear them down. The meanest thing I've done was ask the woman who brought her dog over where she lived. She asked why and I told her my dog needed to do it's business and I was going to bring him over to her yard. She called me a name that I can't repeat here. The neighbors all think I'm mean because I don't like them parking in my yard, either. There are alleys on both sides of their house, and they all have yards, too, but they want to use my yard because before we bought here, it was just a big open lot and they always just used it like they owned it. Funny thing is, it was for sale for 3 years before we bought it. You would think if people wanted it, they would have bought it. They wanted to use it for free. I don't mind kids playing here, but we have a bunch of trees at the bottom of the hill that they like to sled ride on. They smash into a tree, I get sued.
