I noticed that the as yet undeveloped part of the Beltline adjacent to Piedmont Park was in need of one or more caches. This one is located on the periphery of the park as well as close to the Beltline, so muggles shouldn't be too much of an issue. Placed after a rainy weekend, so note that getting to GZ can be somewhat mucky at times. Free parking is several hundred feet away at best, but you get to explore this underutilized part of the Beltline.
