The show at Lake Lanier Islands should be good. Traffic is a nightmare for their light show at holidays. Also there is something happening at Mall of Georgia (exit 115 on I-85) Check out this site for guide of 4th events local to Atlanta.
Define can... Legally?...no. Until the nice police officer comes by and takes whatever you have left away to give to his kids at home?...sure
Oh, I thought this thread was gonna be about the 600 nervous race at Road A with all this talk about fireworks...
Chateau Elan usually has a good fireworks display. Less than 10 mins. from the track, and a lot of fun. You sit out on the lawn in front of the winery, and can bring a picnic dinner.... or grab a pint beforehand at the pub there.
