Thread drift! Hah! Thread drift is what this thread is all about!
Had a good "workout" after work. Playing RotoRooter. Had to dig up a section of sewer pipe, cut a "cleanout" hole, and drag out a bunch of roots. Will have to dig some more later and replace a section, it's partially collapsed where it goes under the foundation. It's the black fiber kind of pipe they used to use 50-75 years ago before they invented PVC.
