Now that fall is officially here, a burst of autumn color in the North Georgia mountains isn’t far off. And as the leaves change, visitors will descend on the region to hike, visit festivals and take in the beauty and variety of mountain life. To help track the changing leaves and plan autumn getaways, Georgia’s State Parks will launch Leaf Watch 2012 beginning Oct. 1 at www.GeorgiaStateParks.org/LeafWatch.
