The American Legion Paul E. Bolding Post 7 is dedicating its refurbished pavilion at 11 a.m. today at 2343 Riverside Drive, Gainesville. The pavilion, which sits off Lake Lanier at the end of Riverside Drive, was part of an amusement park, Chattahoochee Park, built about 1900 on the banks of what was then Lake Warner. Georgia Power bought the park in 1923 and operated it as an employee retreat until 1955.
