Some years ago a friend of mine, a delivery truck driver, had to make a run to one outside of Mendota, Illinois. He said the smell inside was so awful he dropped to his knees with the dry heaves within a few feet of stepping through the door. When he got back to his terminal, his boss took one whiff of him and sent him home early. He had to leave his clothes outside for several days before they were “presentable” enough to throw in the washer.
I had to go out with a rancher in Western Kansas and see his several dead cows. He had drug them away from everything else waiting for the National By Products truck to come get them.
The wind was blowing about 30mph toward the dead cows and I wasn’t expecting to smell anything. In fact I could not see how even an atom could get back to us as we would be thirty feet away from the cows and the wind blowing just how we wanted.
Well we got to maybe 40 feet and the smell just about overcame me. I still do not know how that smell could come back on us with the wind blowing so hard from us to the cows.
One summer while stationed near Camp Zama, Japan, I got stuck in traffic. It was hot and my ‘64 VW had no AC. We were passing a chicken farm and got stuck behind a “benjo” (raw sewage) truck. The stench was unbearable, causing my pregnant wife to stick her head out the window and toss her cookies.
