The very first paragraph is complete crap.
There was no sudden collapse of the Mayan civilization. Their civilization seemed to have arisen in the southern highlands of Guatemala and then spread northwards. Over time, different city states rose and then fell (for many different reasons). El Mirador was abandoned around 150 A.D. Ceren, in El Salvador, was destroyed by a volcanic eruption around 600 A.D. Tikal and Copan fell around the mid 800's. Chichen Itza was a major regional power in 1000 A.D. Mayapan was thriving until the 1400's.
Nothing against Georgia, but I don't see the Maya hiking there for a fresh start.
When there's a Bermuda High off the coast the Washington DC area becomes unsufferable. you end up with HIGH HUMIDITY and NO RAIN. I remember the Summer of 1975 ~ UNREAL!!!
