Drivers license: John just got his SD DL and wrote, We just got our drivers licenses. When you go in you fill out a paper with your address and other info. Handed it in with my Ohio license and was not asked for anything else. Took about 2 mins. to type in info then took my picture. Whole thing was over in less than 10 mins.
