Worst smell

[Grandma Helen]

What is the worst smelling  place you've been?

[officerripley]

A papermill in New Hampshire; doesn't smell like wood like you think it might, really strange smell, almost like a dead animal of some kind. ugh.

[East TX granny]

Pittsburg, TX. That's where the Pilgrim Pride chicken factory is.

Pig farm and an outhouse.  I also agree with the papermill.

Used to live downwind of the old Texaco refinery in Lockport, IL, and it was the most disgusting smell I had, up til then, experienced. Paper mills are pretty awful, too.

My ex-brother-in-law's family egg farm in upstate New York.

My grade school was located near the American Cyanamid plant. On damp days you could smell the chemicals.

Papermills and coke plants (converting coal to coke for steel mills)

[Lynn Patton]

Ashdown, Louisiana. There's a paper mill there.

[Syble]

I live 35 miles from the paper mill in Ashdown, Arkansas and when the wind comes from the east, you can smell it. They shut the mill down a few months ago.

I visited my cousin's turkey farm but don't remember if I'd classify it as the worst smell. I do remember going to a brewery that would definitely make the list.

When my daughter was small, we had to abort a tour of an Anheuser Busch brewery because she got sick from the smell. She remained very sensitive to that smell for a long time. We know because I was often guilty of making it at home. My wife still just barely tolerates it.

I worked for a chemical plant in Newark NJ for a short time and they made asphalt additives and some smelled really disgusting.
Only other things that really smelled bad were foreclosures especially if homeless had gotten and lived in them and did their business with no running water.
