I bought a box of deer antlers at a flea market a while back. The best ones I hung in a doorway; I still had a bunch left that I wasn't sure what to do with, until I decided to arrange them in a display. Kind of like flowers. Or not.
Every day I drive past a spot where somebody field-dressed a deer not far from the side of the road, and the entire ribcage is right there. (Holla! I live in the sticks now.) You have no idea how tempted I am to grab those bones; one of these days it just might happen, if coyotes don't beat me to it.
