I'm lucky enough to live next door to my hunting buddy. We will play a variation of HORSE, you have to repeat the other guys shot (standing, sitting, leaning around tree, etc.). We will also take turns pinning a dollar bill to the block, first on to stick an arrow in it keeps it.
I just built a backstop in my basement, can get a 20 yard shot so we can practice in comfort during the winter. I liked the stuffed animal idea! Got lots of those in the basement waiting to take an arrow.
