Sewage treatment plant near PHL

Used to live about an hour away from one. It's a nasty, nasty smell. Pork processing plants are nasty too, as are chicken farms.

Corn syrup factory in Clinton, Iowa. Uggh.

Rendering plants in the summertime (strong smell of death) in various locations. Yuck.

Athens, TN Bowater plant visible from the interstate. Smells like sulfur, no more no less. Not pleasant but at least identifiable and inorganic.

I wouldn't buy a house downwind but I'd take it over a sewage treatment plant, (wet) pet food factory or chicken processing operation if forced to make a choice among the four.

I can't belive no one has mentioned Terre Haute, IN. Egads.

Before they renovated ONT (10+ years ago), I remember that if the wind was blowing the wrong way you would get a terrible whiff of the cow farms situated off to the east. This was in the days when you HAD to take the stairs in the open air to deplane (no jetbridges). I haven't had the pleasure of flying through there recently, so I don't know if the farms have been paved under yet.

Used to live in AGS, home of the Masters' Golf Tournament. Smell of paper mills would waft 20-30 miles away and it was disgusting.

Now for something truly unpleasant, try an egg factory or factory hog farm. Some along highways in OH and IN. Always try to make sure car A/C is on recirc near there.

To paraphrase Robert Duvall/Col. Killgore - "I love the smell of pig$h*t in the morning!"

Cincinnati smells!
 

I did not know Cincinnati had a nose.

U of I (Champaign/Urbana), if you get the wind from the wrong direction (I think south) the entire town and campus smells like poop. Couldn't imagine studying there being surrounded by the smell of poop.

Taipei is known as the City of a Thousand Odors

From my house you can sometimes smell oranges from the Tropicana plant about 5 miles away. That's a good smell, though. :)
