Have to do it every five years. I filled out the form and turned it in. The young woman behind the counter looked it over VERY carefully. There were a couple of mistakes she let me correct and initial. One of them was hair color. Usually, the eye and hair color are right next together and I just automatically fill in "brn" and "brn".
She looked at me and said no. She was right. There is absolutely no brown left anywhere. I crossed out "brn", put "gray" next to the box, and initialed it. Received the renewed permit today. The picture on it shows grey hair and only one eye, but the remaining eye is still brown.
