I discover that it was probably in the city sewer line so called the city. They came out, eventually said It all looked pretty good after rotojetting a bunch of roots out.
Then I had to drive 45 minutes south to pick up some linoleum for a job. Pickup at Lowe's was awkward but I returned home and then came to get tacos and a beer to cure the near migraine that I've had since coffee time this morning.
It's somewhat better now. Joy.
Time for ibuprofen, jammies, and a movie.
