Deer skull in the woods?

Oh good lord! Just go get it. Why do people think everything will kill them? Unless you've been living in a bubble you won't become ill. Germs are not evil, germs protect us from evil. Don't worry about cleaning it, don't worry about anything. If you must do something soak it in a bleach/water solution for an hour or so. My brother and I hauled all manner of this kind of stuff home and played with it, all unsanitary, and we are two of the healthiest people I've ever known. Buck up and live!
