When one of my dogs passed away, I planned on burying him next to the previous dog that passed. I misjudged, and dug up the first dog. I jumped into the hole, and put his remains back where they were supposed to be, and the fellow operating the back hoe moved over a couple feet. That dog had been wrapped in a heavy blanket, so all the bones were contained. Mistakes happen, and you just have to make the best of them. I do have my water and electric lines marked with underground marking tape. It is a requirement here for all buried utilities. Propane is above ground, so leaks will be evident before the explosion happens. The only one that isn't marked, is the line from the septic tank to the leach field, but where the distribution box is located, that is on the map. Hope to never have to dig that one up.
