I was using my backhoe to hook up a neighbors water line to the main plastic water line, that was somewhere under our driveway. I stopped digging about four feet from where I thought the main line might be, and decided to dig the rest of the way with my shovel so I wouldn't cut the line with my backhoe bucket. Just as I started to dig, one of my neighbors, who acted as our water line inspector, shows up and pulls out two small rods out of his shirt pocket, holds them out, the rods crossed, and he said "the water is right here". I placed a rock on the spot where he pointed and started shoveling toward it. The plastic pipe was 5 feet underground and just 4 inches from where he directed me to dig. I was sceptical up until then, but I am a firm believer now.
