How exactly do these work? When I was in college, people used to say that the Indians got their tags for free, thus the different designations. Then I later heard that they don't get them for free, that they often cost MORE than a regular tag, and that the proceeds to go the Indian tribes. So what's the real story? Who pays what? What is the benefit for a person having one? Does any money actually go to local schools, roads, etc? Not trying to make a political statement, but i've noticed a lot more of them lately, and I was wondering exactly what their purpose was.
