When I was in 2nd and 3rd grade we lived on a little Forest Service station up in NE California just a few miles from the Oregon border and Cedarville.
Being as there was 5 of us and we ran around all over the place we eventually had a pretty good collection of Indian artifacts. We never actively hunted them but picked them up as we found them. Who knows what happened to them by now. I do remember trying (unsuccessfully) to make my own arrows using a few we picked up.
