While working our front yard tonite, I got a solid hit , dug 3 inches found a steel U bolt,,,,the handle to a septic tank I didnt know I had. If this were an episode of "Lost", I would have opened it,, but nawwwwww,, I just let my imagination run with it.
This one is an old un used one , The one I'm hooked up to is out back where it belongs. This makes the second old one I have located on my property in the front yard.
