I just wanted to take a moment to thank everyone for their incredible
advice. I tried as many of the suggestions as I reasonably could, and
didn't tackle the ones that I felt were beyond my ability (I'm
recovering from some broken bones and did NOT want to risk climbing on
the roof!). When it became obvious that I couldn't fix it, I finally
gave up and called Roto-Rooter. :-(
Thanks again, everyone, I really appreciate your time and effort in
trying to help.
