the tribal agencies have been beta-testing the new tribal database for the last couple months and it was released to the rest of the agencies with an OLETS terminal a week or 2 ago. you can now run Cherokee, Muscogee, and Osage tribal tag just like you would a standard OK plate!
It's about time. I can recall having to call the tribe on the phone every time you wanted to run a tribal tag. Sometimes they didn't have it in their own computers and they had to look it up by hand. Ha...30 minutes for a return. Good for investigations only I suppose.
