Do they normally comb the privately-owned beaches that border the public beaches too? A lot of Ocean Shores is privately-owned, and it's bordered by private beaches. Most beach wanderers are accidentally trespassing.

Also, how do they clean the beaches where automobiles are not allowed? Part of Ocean Shores beach doesn't allow cars. And what about the miles of sand dunes, rocky beaches, jettys and other places cars can't go? How do so few people keep clean so much coastline? Are they training seagulls and deer to pick up litter? It doesn't scale...
