There are many great places to play golf in Atlanta and one of the great things is that you can go to many and join groups that are not foursomes.

A couple of the courses close to you are Bobby Jones:
384 Woodward Way NW
Atlanta, GA 30305
Phone: 404-355-1009

Also North Fulton Golf Couse at Chastian Park:
216 W WIEUCA RD NE
ATLANTA, GA 30342
Phone: (404) 255-0723

Both are public courses and are very reasonable. You can go any time and put yourself on the list and they will match you up with people to play with. It is a great way to meet people in a new town not to mention enjoy the great Spring weather in Altanta. I hope this helps - Good Luck!!
