Is the shoreline at Mammoth pretty clean? I heard that Dunlap shoreline is covered with goose crap these days. It is a shame if that is the case because it used to be a nice place for kids to fish. I want to take my son but he needs some room to run around once his attention span is used up. I would prefer him to not have to run around in goose crap. I hadn't thought of Mammoth.
