GONE!!!
stink

At one point I left to to other things - there was only so much I could do... Redneck came running over very excited. He said he got rid of something. "What?" I asked. He said "I got rid of the stink!!!" Oh that. UH. "How did you do that???"   Anyway someone never got the drain pipe vent put together drain was venting into the wall. Redneck stuffed some plastic in the hole for now. Much more pleasant around there.
