I have you all beat, hands down (and I grew up in Wisconsin).
When I worked at the Art Institute of Chicago, I assisted an artist named Doris Salcedo install a sculpture, during which time I had to take dried cow bladders, soak them in water, and then stitch them to a wall to cover a niche she had cut in the wall and cover it with the bladder...to wit:
Nothing like the smell of 50% death 50% cow pee. Opening the buckets of soaking bladders in the morning always brought forth am involuntary heave. And I worked with these thing all day every day 12-14 hours a day for two weeks.
That smell will haunt me for the rest of my days.
