My little canoe and I prowled the Rum River last week. The flotsam and jetsam pictured above is left by the 'rats' who dump their non-biodegradables into the stream. It's just the tip of the trash-berg. I spent an hour collecting the worst of it, all in an area of about 400 square feet:
Two full bags as well as a couple of 2-liter pop bottles—one of them full of root beer.
It was only a dent, but where I did do a clean up it looked better already. I might make this a habit.
The most disgusting item was a can of Budweiser Clamato beer.
