I had a knock on the backdoor @ about midnight. He said," Sheriff's Department." I had not called them. I answered the door with a gun behind my back. When I turned to lay it on the table, he said that I scared him to death! He was lost.
this is very upsetting. I don't doubt your wits, as you have made it this far(you claimed you were an old man in your post). This guy is lucky you didn't point the gun at him. He wasn't the Sheriff's Office, right? If not, he is a very shady character in my book.
