If you don't already know, the gas situation in the Southeast is ridiculous. It's downright crucial in the ATL area!
Seeing as I don't want to see anyone on the side of the road (including myself), here is a website that will help you. Just go to www.atlantagasprices.com and look on the left panel for city location. You can also click on the time frame for more current info. (i.e. 24 hours, 16 hours, 4 hours). Keep in mind that this is not a guarantee but it definitely is a lead. And let me not forget, www.11alive.com can lead you to station w/gas, also.
I think I need to start checking out public transpo. What's the old saying, "Marta is Smarter."...
Oh, by the way. A helpful move (note: this can be painful) is to adhere to the speed limit. Yeah, I know. It hurts to do but makes that tank of gas last much longer.
