As summer begins to fade, Sky Valley plans to mark the last days of the hot season with a party. The Last Days of Summer Celebration will be from 5:30–9:30 p.m. Saturday, Sept. 5, at the Sky Valley Pavilion, 568 Sky Valley Way, in Sky Valley. Participants will feast on barbecue and listen to the live sounds of Sweet Charity, which performs classic rock ’n’ roll as well as southern and country rock favorites.
