I got a call a few summers back for a dead deer. I asked how long it had been there. "Well, we've been smelling it for about two weeks." 85* every day, and with all that info, you still can't imagine what this thing looked like. It was moving. If there wasn't half a million maggots, there wasn't a one. I put disposable gloves on and grabbed ahold. Attempting to drag it to the truck. Only made it a foot, when the entire pelvis disconnected. I managed to get it into a couple construction bags and into the truck.
My next stop was 30 miles away. I should have reversed my route of course. So all the way to the next stop, I can smell this foul thing. I just knew I stepped in the goo or got splattered. My reading glasses I hang on the front neck of my t-shirt, and apparently had touched them with my gloves on. The smell was inches from my nose the whole ride. I did not charge enough for that one.
A hitch hauler is very useful.
