Sad to say, I live in a city with a little city sized lot.
But my house is 82 years old and an old sewer line (no longer in use) ran along the edge of my property. People threw out all sorts of stuff. I have old medicine bottles and buttons. At the back of my little lot is where they used to burn their trash (way back when) and I have dug up a lot of bits of metal and glass.
I really do enjoy reading about other people's finds and someday I'm going to pack up my MD and go dig somewhere ......
