    Scrap Yard Shocker!!

    Went my local scap yard and picked up 11 lbs of brass/bronze. $44.00+ Tax. At this price I might just as well buy new stuff, I think. Have to check prices online I guess. Man, I almost had another heart attack. He's the only game in town so I guess he can do what he wants. Ron
