Plastic shotshell wads that migrated from the Warnimont Park shooting range and washed up on Grant Park beaches were picked up by volunteers during the Friends of Grant Park 2015 Spring beach cleanup. Nineteen pounds amounting to approximately 3,268 pieces were collected. The first photo shows all of those pieces spread out in a single layer… the second photo shows the same pieces inside a plastic bag. The only time the range operators were ever ticketed for littering by the DNR was in 1989.
The white bar in the photo below is a yard stick.
