What a great find! My number came from a conversation I had with my dad back in the 60s. We were talking about how much less expensive UNC was than the schools my bother and sisters went to. We all four graduated every two years from 1966-72. I'm guessing that he was talking about all four years I spent at UNC and not just one year and included room and board etc. Damn it was cheap! Good job setting the record straight.
