I love all the repurposing of cast-off into treasures for the garden. Paul, I really love your finds blended together. One of my favorite places to shop is a salvage yard. I usually go with three other gardeners and the big machines usually stop while the guys take a break and laugh at us old ducks scurrying about digging into piles of nails, wire, engine parts, etc.
I like to collect all old wooden handled garden tools and attach them to a long section of chain link fence that dissects my yard. This hides the chain link and makes a wonderful conversation piece.
