Gardens and Parks in Georgia

Gibbs Gardens in Ballground, Georgia is being called a "best-kept secret." (Funny, I thought that Cohutta Springs Conference Center enjoyed that title!)  ;-) But... it does appear that this is a fairly new garden, or at least, is newly opened to the public, and contains 200 acres:

Hills and Dales in LaGrange (formerly Fuller Callaway's mansion home): It's a nice garden, with boxwoods dating back over a hundred years, and some gorgeous walking paths. I believe the former owner was a brother of the Callaway who started Callaway Gardens.

Callaway Gardens in Pine Mountain: A year or so ago, we went to the Botanical Gardens in Atlanta--all very nice gardens; so, Gibbs Gardens is a nice treat to look forward to...
