I lived in Peoria for about 3 years when I went to Bradley. I never could put my finger on the smell that town has, but I think I finally placed it. DMS!! That's why it smells like corn / beer / bum piss on certain days of the year.
I thought it was the soy beans being dried/malted...
ADM in Peoria is/was (not sure if it still is) the largest producer of grain alcohol in the US. So yeah, they pump out the smelly stuff down there.
Bum piss...I LOL'd! Brought back thoughts of work last night.
