The people who lived here before us dumped a whole bunch of nails, and glass, and metal at the back of the property. We were unaware of this until we started tearing out trees to make way for a clearer horse pasture. Now the debris has been somewhat scattered around a certain area of the field. We can't bring our horses home until we get this taken care of. My question is does anybody know of a place where we can rent a fairly large and powerful magnet? Or a place we could buy one? What kind of magnet would work best in this situation? Please, any help would be greatly appreciated.
