My mom has told me many things about that era. It was an exciting time to be a young single woman. There were opportunities for work and for service that were unknown before that time. And Momma worked at Camp Claiborne as a secretary which meant that when she went to a dance there were hundreds of young men lined up to dance with the beautiful young woman she was. (She's still beautiful.) She told me she danced a million miles during her time there. And dancing was fun back then. I am sure she can still show you her jitterbug moves at age 90. I'll never forget the day when I was a teenager when she and her brother showed us how it was done.
