Guys,
These nails are a bummer to say the least.
I have one area that a previous owner must have used for a trash pile since I have had two flat tractor tires and several flat truck tires from this one area.
I finally got one of those magnets on a stick and went around looking for nails and metal. The attached is what I found...a couple of pounds of nails, old bolts, and sharp metal pieces!
