46 years in the ground

I was digging in the garden today, trying to prepare a spot for my hardy hibiscus.

I unearthed a steel fencepost. My guess is that it was buried at the time the house was built (1961).

46 years in the ground.

It is like this every time I dig in the yard. Rusted metal, broken glass, shattered bricks, etc.

Obviously, no serious effort was made to clean up. They just spread a thin layer of topsoil over the whole mess.
