Yes I have, but I've never been on one. I've thought about doing it however.
A while ago, I had a dream, that I believe was a message. It said don't chase the Coyete..walk with the White Wolf. And since then I have made a lot of changes in my life. Which includes speaking up when I see something that is wrong. Of course that has caused a lot of problems.
But if Russell Means and the other activists can do it and risk jail time and bullets than I can stand a few people being mad at me.

Have you and your wife heard to AIM? (the American Indian Movement). I've been trying to find a local chapter here in Georgia but no such luck.
