Some paper mills in the south smell much worse than anything I've smelled in NJ. Much worse than fresh skunk too.
The scariest stuff in the air I ever encountered was driving by a chemical plant near Niagara Falls. There was no smell at all, but it didn't feel like we were getting enough oxygen with each breath.

Basically smells like vomit. Someone stole a bottle in my high school and it broke in his jacket pocket. Talk about an idiot.

Probably the last thing you ever smell too.
