Gotta be careful with dumpsters. I bought and butchered a couple pigs each fall for several years and a couple of those years I was in a complex where a pair of dumpsters were provided for garbage. I had a buddy who raised sled dogs and he’d take the carcasses and freeze them as a rule but one time he didn’t have freezer space. On that occasion I just rolled the hides up with the flesh side in starting at the tail and finished with the pi’s head setting right on top of the roll. Both of these went in the dumpster the day before pick-up. On the morning of the pick-up I heard a god awful screaming and racket in the driveway and looked out. Here the driver of the truck was darned near hysteria, wet pants, the whole nine yards. When he whipped that cover back here were the two pigs glaring up at him. Not good. Cops, the whole nine yards.
If you use a dumpster be sure everything is wrapped in opaque plastic or heavy trash bags like the black 50 gallon yard bags. I’m guessing a bloody deer carcass probably elicit the same king of reaction the pigs heads got. Man, if some old woman opened a lid and saw a chopped up bambi in there she could have a heart attack.
And the suggestion of in the back of someone’s pick-up was tongue-in-cheek.
