We stayed at a lovely inn in Midway, Utah some years back that was situated next to some big crop fields. The weekend prior to our stay they held a beautiful wedding for some young bride and groom. You can guess what the farmer put down on his field right before the wedding! It was still a bit “fresh and earthy” smelling when we arrived.
gawd yes....going in that hog barn is aweful... and they have these huge fans blowing air through them to cut down on gasses.. it surprising how much they get off those places.. its a lot!
