It's really amazing how much damage four men and a backhoe can do in a day, even if that's not their intent.
We had expected that the new sewer line would be put in by Ditch Witch, but no, it was so deep (7-9 feet) that a man had to fit fully down in the trench, which meant a full-size backhoe had to maneuver in our back yard. The clay -- and our subsoil is nothing but 100% clay -- was piled all over the yard and sidewalk, and then the rain started, and now there is slippery, sticky mud on everything.
