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.
I think the question should be "Do the young comanches want to hunt down bison with arrows and spears?" My guess is not anymore than the kid who bagged the first bison wants to shoot with a rifle from the 19th century.
