Does Charlie bury his elk legs?

Yes. He gnaws on them and then buries them and then other animals dig them up and gnaw on them and bury them somewhere else and then Charlie finds them, and unburies them, and gnaws on them, and buries them somewhere else.
When I saw how much Charlie loved them, I stockpiled elk legs in my freezer to give as special treats and now there are elk legs in various stages of gnawedness scattered all across the land around here.
