a bit ago, I had to go to Iowa for work, setting up a new branch office.
I had to keep my mental filter on because literally everywhere in Iowa smells like pig shit. Even the cities (which, to be fair, usually smell like shit.).
I wasn't there long enough to go nose blind, but it was a few months.
This map just... puts some numbers as to why... also makes me think Indiana probably smells like pig shit too... maybe not as much...
