I am in the process of having an aviary built for my peacocks and I was telling the person who is building it that it's a shame that someone or some company couldn't use the old, used nails that we are pulling out of the recycled pallets that we are using. We have tons of nails from taking the nails out of the pallets. Well, it just so happened, that I was reading the ads in our local newspaper and what did my wondering eyes see. There it was.......An ad from a guy looking TO BUY rusty/used nails. I couldn't believe it. I try to recycle as much as I can but who knew that someone would want to buy used nails. Does anyone know why he is wanting to buy used nails? What can someone do with used nails?
