Couple of laborers I knew when we worked on the Shuttle complex used to do it on weekends. One of them found a pretty good nugget one weekend and was showing it off at work. He was standing on the launch mount forms before we poured the concrete and he dropped the nugget into the formed area. Talkin' 50' deep and 100'x100' and loaded with rebar every 18" :eek: . He sent his entire laborer crew in through the side to try and find that nugget :realcrazy::eek::lol:
