Anyone lose a pickup bed liner?

We wondered how something like this bed liner came to be in the Monongahela River. No good answers. It's among the largest items we've pulled out; probably second to the car bumper from a couple years ago. (Click photo to enlarge.)

Anyway, we had a good day of "fishing" for litter on the Mon and really got the Morgantown harbor area looking good.  In this photo you see the liner and our other ''catch" with crew members Carol on the left and Hannah on the right.

Thanks, Carol and Hannah. They worked hard, as you can see in this photo, left. Each bottle, Bud Lite can, etc., must be picked up individually. There's no other way. So this is labor intensive, and it takes a real commitment to the environment and the Earth and the Monongahela River, to get this job done.
