You could try getting mugged or perhaps beaten in an alley.
I grew up in Atlanta and cant imagine why you would choose it as a vacation spot.
But if you must, you could check out Underground Atlanta, the CNN center, Fox Theatre. You could go make fun of the nerds at my alma matter, Georgia Tech. Check out the Buckhead area for some good restaurants.
Ill add more if I think of anything else.
Check out the "Sun Dial" restaurant. Probably one of the oldest and most famous restaurants in the city.
Also go the top floor of the Peachtree Plaza for a great view of the city.
Also go see Stone Mountain, just east of Atlanta. A lot of history there.
Oh yeah, duh...Georgia Aquarium. I think its the biggest one in the country.
IF the weather does let up and you decide to play golf, take a little drive east to play Cherokee Run golf course...you wont be disappointed, especially if you play a slight draw. Its an Arnold Palmer inspired course and just about every hole has a slight draw built into it. Jack would shoot 85 on it.
