Anyway, the time had come to do sort things out and salvage what was salvageable. I really didn't expect much, because it is all backed up to a prairie; unless it is hermetically sealed, there will be wildlife seeking shelter and the driveway slopes downward towards the storage area.
I was actually surprised. Much of what was in it had composted down to a scoopable layer, but there was quite a bit left in good shape.
What could it be?
This shows the fallibility of memory. I thought I had last walked into storage about thirty seven years ago. A 'Star Wars" Burger King glass (real glass) shows human activity much later than that. Science my friends, science.
