Kudzu the demon vine
Bob if I recall you'll be in the Greenville SC area as well as Atlanta and Charlotte. Anywhere outside of Atlanta towards greenville or Augusta ;Travelers rest grey court outside of Greenvile or south of charlotte on 77 towards Columbia SC. are loaded with the demon vine. Public transportation is likely to be a problem it's not one of the souths strong suites. I'd consider renting a car for a day or two in any of the major cities to get out where you'll get the best shots of kudzu. And as far as the summer heat it's the price we pay for our winters.
