About 1 1/2 hours after the plumber arrived, this is what he pulled out of our drain.
It was like pulling the plug out of a bath tub. Once out, all the water gushed out. What didn't flow out nice and easily was the yucky dirt and crud. So, I got to scrubbing (just like my days at Chick-Fil-A...if you got time to lean, you got time to clean).
