People are garbage.
I walk the same 1/2 mile of gravel with my dog every day, and just about every day there's something new to pick up. I can't tell you how many Busch lite cans I've picked up, but I do sometimes fantasize about melting them all down, forming a hammer, and then murdering every littering asshole I encounter with it.
Oh, and apparently, the Sheyenne Diversion is the perfect place to get rid of things you don't want.
Over the years, I've found pallets, concrete chunks, a vacuum cleaner, discarded house plants, a 6ft spruce tree, two dead rabbits in plastic grocery bags, and what looks like the leftovers from an entire picnic. -- And that's just the particularly atrocious crap off the top of my head.
What blows my mind is the number of dumpsters and other trash receptacles these shit bags must have driven by to go dump their crap in the diversion. It's like some people go out of their way to be the scum of the earth.
