I'd like to say I did it on purpose with some intent, but I just went cheap by burying the head and letting the bugs and worms do their thing. I didn't even skin it first. Just buried the head with hide on it. Left it there for 16 months. There wasn't a shred of hair or meat left on it. Although the brain cavity was a milky goo,vwhich was pretty gross but nothing sa good hose couldn't take care of.
