What did everyone here do? I spent 4 hours cleaning Bear Creek, a stream in the Rockies outside Denver. Got about 4 leaf bags of junk out of it, Almost entirely plastic bags and styrofoam. Put on my waders, got right in the muck and cold and removed all the crap that collects in the rock snags and breaks where trout live. . Also got a tire, an air mattress, plastic water bottles, and about 50 tennis balls. Go figure. Those damn plastic grocery bags are everywhere.
