Hobgood maybe this will help? Meeting location is Atlanta Georgia, at the Perimeter Mall on the north side of Atlanta.
Address of mall: 4400 Ashford Dunwoody Rd, Atlanta, GA 30346
The Perimeter Mall is a shopping mall in Perimeter Center, Dunwoody, Georgia, a suburb of Atlanta, near the interchange of Interstate 285 and Georgia State Route 400. It is the second largest shopping mall in the state of Georgia.
Also you might want to pick which parking lot, there are alot of them. I would go with the one in front of the "Perimeter Station" on the north west part of the mall. At a intersection of Perimeter Center Pkwy NE and Perimeter W.
Actual address: 120 Perimeter Center Pkwy NE, Atlanta, GA 30346
Have fun take pics, I hope the weather is good and have you touched base with the mall owners to see it it is ok, since you will be on private property? Never hurts to let a person know what your plans are for THEIR parking lot.
