By By Jean Tarbett Hardiman The Herald-Dispatch HUNTINGTON, W.Va. (AP) - Rick Millen thinks of life in three acts. Act 1 is youth, which is a lot of fun and the time when you go to school and get educated. "It's great, but everyone has to grow up," said Millen, who got his undergraduate degree at the University of Maryland and studied at the University of Georgia to become a doctor of veterinary medicine. Next comes Act 2, when you start earning a living, raising a family if you so choose, and paying off a mortgage.
