I used to go past the monument 3-4 times a year and each year I would wonder what was taking so long... Finally my father stopped and we went and saw it, walked around and learned all that you mentioned.  I have looked at it whenever I feel like quitting or giving up and realise that I can't because of what they're doing and how.  Growing up near there I learned a lot of history that isn't normally taught to kids in other areas, and the depth of our education on Native Americans was extensive compared to what other students receive in other states.  There's a lot of pride in those hills, along with a lot of tears, sweat and courage.  This is a great cause, and worth a couple of dollars from anyone who cares to perserve history.
