Elvis Presley never held a concert in Gainesville, but just as his career was taking off, he made a pit stop here, according to a Hall County man whose brother met the famous singer. The Gainesville High School Class of 1966 held its 50th reunion recently, and Dwight Whitmire was enlisted as an Elvis impersonator. It was appropriate because he told his classmates the story about the time his late brother, “Flossie” Whitmire, encountered the real Elvis outside a Gainesville gas station.
