I watched a strange beat up car come down our road yesterday. Watched where it went (we are on top of a hill, so I can see mostly all of the road). It stopped down by the neighbor who has 2 trailers, his plow truck, tractor, and implements all lined up by his fence. I think the guy was "shopping" the neighborhood.
The road is a private dead end road. It is exceptionally rare to have a non resident drive down the road. The neighbor is away camping, so I gave him a call asking if he was having someone "watching the house" for him. He said no and he'll check his security cameras.
Stuff like this makes me paranoid....
