Some quick thoughts...
1. Atlanta is comprised entirely of one way streets. The only way to get out of Downtown Atlanta is to turn around and start over when you reach Greenville, South Carolina.
2. All directions start with, "Go down Peachtree..." and include the phrase, "When you see the Waffle House..."
3. Peachtree Street has no beginning and no end and is not to be confused with Peachtree Circle, Peachtree Place, Peachtree Battle or Peachtree Corners.
4. Atlanta is the home of Coca Cola. That's all we drink here, so don't ask for any other soft drink... unless it's made by Coca Cola.
5. Atlantan's only know their way to work and their way home.
6. Gate One at the Airport is 32 miles away from the Main Concourse.
7. It's impossible to go around a block and wind up on the street you started on. The Chamber of Commerce calls it a "scenic drive" and has posted signs to that effect so that out-of-towners don't feel lost....they're just on a "scenic drive."
8. The 8 a.m. rush hour is from 6:30 to 9:30 a.m. The 5:00 p.m. rush hour is from 3:30 to 6:30 p.m. Friday's rush hour starts Thursday morning and lasts through 2:00 a.m. Saturday.
9. Reversible lanes are not understood by anybody... especially those of us who live here.
10. "Sir" and "Ma'am" are used by the person speaking to you if there's a remote possibility that you're at least 30 minutes older than they are.
11. "Sugar" is a more common form of address than "Miss". So is "Honey". "Honey" is always used by Waffle House waitresses.
12. Ponce de Leon Avenue can only be pronounced by a native, so do not attempt the Spanish pronunciation. People will simply tilt their head to the right and stare at you. (The Atlanta pronunciation is "pont duh LEE-on")
13. The falling of one rain drop causes all drivers to immediately forget all traffic rules; so will daylight savings time, a girl applying eye shadow in the next car, or a flat tire three lanes over.
14. If you're standing on a corner and a MARTA Bus stops, you're expected to get on and go somewhere.
15. Atlanta is pronounced "LAN-uh".
16. Construction on Peachtree Street is a way of life, and a permanent form of entertainment, especially when a water line is tapped and Atlanta's version of Old Faithful erupts.
17. Construction crews aren't doing their job properly unless they close down all lanes except one during rush hour.
18. Atlanta's traffic is the friendliest around. The commuters spend hours mingling with each other twice a day. In fact, Atlanta's traffic is rated number 1 in the country. You will often see people parked beside the road and engaged in lively discussions.
19. Atlantans are very proud of our race track, known as Road Atlanta. It winds throughout the city on the Interstates, hence its name.
20. Georgia 400 is the southern equivalent of the AutoBahn. You will rarely see a semi-truck on GA400, because even the truck drivers are intimidated by the oversized-SUV-wielding housewives racing home after a grueling day at the salon or the tennis match to meet their children at the school bus coming home from the college prep preschool.
