One crew of bright orange T-shirts and another of white jumpsuits swarmed the American Legion Paul E. Bolding Post 7’s property off Riverside Drive on Tuesday.The veterans organization’s headquarters building underwent a one-day blitz of renovations, interior and exterior, by a crew of Home Depot volunteers.And prisoners from the Hall County Correctional Institution, under watchful supervision, were laying the groundwork for improvements to the century-old Chattahoochee Park Pavilion.Post Commander Dave Dellinger was beaming as he watched the flurry of activity. Such projects simply don’t fit into the post’s budget.“We couldn’t do it — no, not at all,” he said. “We sometimes have trouble paying the bills.”But, as commander, Dellinger said he recognized early on that the post needed to make some long-overdue repairs, especially at its main hall, which was built in 1982.
