Forty-seven area residents attended a program hosted by the Knoxville Historic Preservation Commission last night.  Commission member Carolyn Formanek says the program, by Will Prather and entitled “Historic Towns of Lake Red Rock”, was the second in a series of monthly programs relating to the history and heritage of Knoxville.  Prather spoke on a variety of subjects, including early Red Rock, the Red Rock Line, and early steamboats on the Des Moines River, among others.
