Indian Tags

[tulsa1603]

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.
