I had this container in place at another location. Who knew it wasn't in park land?! It wasn't clear who owns that property, so I moved it. Drat. This container doesn't fit just anywhere. It's a mystery size.
So now it is definitely in a park but hidden in a place where it can fit. Please be stealthy. Please close it securely. Cover it up. Don't drop it.
Congratulations to NoBlueCircles on the First To Find.
