Georgia Mountain shows are good, but I believe that the Eastman shows are a little better. Can't go wrong with either.
What part of south Atlanta? The southside pretty much sucks.
Recreation depends on what you want. You can pretty much find anything there. There are shooting ranges all over the Atlanta area, both inside and outside. There are oval tracks and road courses in the Atlanta area, so whichever racing you prefer, you can find it.
Any type and quality restaurant you can find in metro Atlanta. Night life is marvelous, again, anything you could imagine.
Yes, traffic sucks. enough said on that subject.
What brand of hotel did your company put you in?? There are nice but relatively inexpensive hotels on the southside. Try to find a Comfort Inn or any of the Clarion hotels, which include Comfort Inns.
Go to Buckhead or just about anywhere on the northside to have fun.
