Bah, the indians are too busy building casinos these days to hunt buffalo / bison. I doubt they want to go back to the "good old days" where, for all their greatness, they never invented the wheel.
I'm not sure that inventions or casinos should be the standard here.
We took away the Plains Indians culture that had developed in tandem with the buffalo with our inventions. A little nostalgia and humility wouldn't be amiss.
Personally, I'd love to see a young Comanche on horseback trying to bring down a running bull with an arrow or lance the way his forebears did.
