Dairy farms are nothing compared to pig farms. Absolutely foul. The smell is so penetrating it feels like you can smell it through your eyeballs. Cow manure you can get use to, but I could never get use to pig shit.
Papermills are also infamously smelly, though you can get use to those pretty quickly.
