Well, found a dead possum in backyard. I think our new Hawk neighbors did their thing to this critter. Well, I picked it up with a shovel, and put it in industrial ply garbage bag and duct taped it so no air could get out. Put in garbage bin. My wife and neighbors wife are looking at me saying that is not going to work. Well, they were right. Next day, a billion flies and the smell that goes on forever. So , I got big, I TOLD YOU SO. What did I do wrong. In theory, it should have been okay? Industrial bag. Went and buried the darn thing, plastic bag and all.
