Dang Jamie, you took the words right out of my keyboard! I have an old book, that I stole, I mean, forgot to take back to the Jr. High school library, and it has the snow snake, and one similar to the one grunt has, and it was a small hoop, with a weave like a dream catcher, and it was rolled on the ground, and the participants had pronged spears for lack of a better description, and they would try to hit the hoop, as it rolled past them, or down the hill. Something similar but in the air, and with bows also.
