I got a call from a woman in Barre who lost her Toyota Prius key last Fall. She was still able to drive her car but unable to lock it for the last 8 months. She said it would cost about $200 to replace it. The area where she thought it would most likely be was next to her parking spot in a very congested neighborhood. It was a mix of gravel, flowers and grass, and about 200 years of heavy human activity…..lots of miscellaneous, overlapping scrap metal signals!! After about 2 hours of intense digging, it was starting to get dark and I was about to head home, very disappointed. But, I checked a weak, spotty signal, dug down about 2 inches and there it was! It was right where she thought it should be. A tricky but satisfying hunt!
