I am late to this post, but --- an old timers trick that we have used elk hunting and having to leave some of the elk meat overnight was to hoist the quarters into a tree with rope. Then take you hunting shirt off and hang it there with the meat. The human scent will tend to keep predators away from it. Works for coyotes and black bears; but I don't know about Grizzlies. We don't have any Grizzlies in the areas we hunt in Eastern Oregon!
