I had a chance to go though the insulators on this truck about 15 years ago. Mostly commons as seen in the photo before sorting but a sizeable number of better quality pieces, both porcelain and glass, were buried under the heap. The owner of this truck mentioned that a bus full of insulators from this same salvage yard was driven to Sandpoint, Idaho in the 1970's. I realize that we're going back more than 40 years but I'm wondering if there is anyone here from the northern Idaho area that knows what happened those insulators?
