" I have a lab filled with millions of dollars’ worth of equipment, and I can tell you none of it works as well as a good dog’s nose. I’ve witnessed canines hitting on hundred-year-old remains. What they even smell, none of us can tell you. At that point, there’s no organic matter left; the bone is little more than a dried sponge. But the dogs always know. "
