The clove hitch excels in all kinds of outdoor applications. It's great anytime you need to quickly tie a rope to something - a tree, tent pole, fence post, truck hitch, hunting buddy.
I use it to anchor my pack rope to the sawbucks on a packsaddle. It enables me to sling elk quarters on my pack horse and never worry about them slipping off. Best of all, it's easy to tie. Once you learn the technique, you can tie it in the dark, and without even thinking about it.
