i have to agree with Borjn back in the early seventies our barn burnt, dad got the cows out but the bull and some pigs got toasted.burning flesh stinks.still remember seeing a firefighter running after a half roasted pig to put it out of his misery.
another smell on the farm is a fresh cow that didn't clean after calving,boy can that afterbirth stink after it rotted inside the mother for 1-2 weeks. sorry to gross anyone out , i have worse stories,you see everthing on a farm.
