I tried to place the word 'overhoop' (upside down) in a spatial context. When looking for a location I found this place where they used to dump garbage. It now look like a tidy hill covered in grass. Not looking suspicious at all. When I did research on those kind of 'hills' I found out the also dumped a lot of chemicals and other waste there.
I guess what I'm trying to say is… When you dig, you never know what you will find and how it will look. So what I did was starting to dig there myself. Turning the hill of waste upside down.
