     I got my first driver's license in 1953 by taking driver education in my first year at Central High School

in charlotte, North Carolina. Four years later when it was time to renew my license I was a married woman

Henry and I were living in Batimore, Maryland Two weeks before my 20th birthday. Henry drove me to the

motor vehicle office on a hot July afternoon. When I got to the office and showed to the man behind the

counter my North Catroina driver's license ready to renew, the man told me that I was under age by Maryland

law since I was not yet 21. "Mr Henry Smith your husband to sign for you," he said.

     I argued, pointing to a very large belly of mine, "I am married. I am having a baby. Why shoud I have to

have someone sign for me to drive? He answered coldly, "it's the law, madam?"

     Henry encouraged me to calm down, just go ahead and get the license and be done with it.

     "No" I said. I refused to have him sign for me. So I left without a Maryland license.

     I called the North Carolina Motor Whice Office and renewed my NC license by mail-using my name Susan

Brown And thus it was for the next twelve years. Since Henry was in the army I could drive under my home

state licene. By the time Henry left the army we were once again liviing in Maryland and I had to take the
