years back in a fly shop on a very popular river here in Northern California I ask a young man if he stocked lead bb's. He said the shop no longer sells product that contain lead. They are fighting hard to keep the river(s) clean. I was a bit shocked and asked him if his neoprene waders where two colors... very light from the hip down while being natural above. He replies why yes, they where, how did I know that... I told him the the mines up river of the shop dumped millions of gallons of metal heavy toxic water into the river daily and has for decades...the water is so acidic as to bleach neoprene ... I said that banning lead BB's seems a bit over the top. He looked a bit puzzled and walked away...
