Oh man,I'm a truck driver and used to do a lot of landfill work taking trash from the transfer stations in 53' containers and possum belly tipper trailers to the landfills.
You can imagine some of those loads were pretty nasty so I've been around some bad smells,some of the containers came into the docks on barges and sat in the hot summer sun for days before getting loaded on trucks for the landfill,we'd back them on the tipper open the doors and about puke.
As bad as those were there was this one guy that came in from the coast with a trailer load of shrimp waste from the cannery down at the mouth of the Columbia river in Astoria,his loads were the worst far and away,no one wanted to get stuck in line waiting behind him.😷 Worst smell ever!
