Georgia was established in 1732, the last of the original 13 colonies. One hundred twenty-nine years later, she seceded from the Union and was "absent" for nine years. On July 15, 1870, Georgia was restored to the Union, the last of those states which had broken away.
I have visited Georgia on several occasions, and these for an amount of time that "counts," not just a drive-thru on my way to somewhere else. From the hills in the north to the swamps in the south, from the western peanut fields to the southeast coast, the state is blessed with true and varied beauty.
I could name some favorite places, but that might be at the risk of offending someone whose favorite Georgia "spot" is in a different locale. However, no offense intended, I have to mention the Brunswick-St. Simons Island area, and certainly Savannah, Skidaway and Tybee Islands. Perhaps one of my favorite lowlands features is the salt marsh, and of course I've always been partial to the seashore.
By all means, visit Madison. Warm Springs should be on the itinerary. While you are there, visit nearby Callaway Gardens, too!
