I believe the request was for the "Atlanta area", not north Georgia.
Mistake Not, my joking with Randy aside, it's more like 35-40 min from GA Tech on a weekend morning. I'm in Vinings and flew a SR22 at LZU for 4+ years. Just watch you velocity on 316 when traffic is light as I've seen plenty of ticketing along that route when traffic is light. You may want to get a Peach Pass too. It makes it nice to get around small traffic issues.
FTY will be pricier if you want hangar space as they just have big hangars. Not too bad if a tie-down is acceptable, but since you asked about hangars it's probably not. I wish someone there would get their act together and close down the little runway 9-27 and put t-hangars in that area. FTY is a nice little airport and Stockmar and Paulding county are both nearby for cheap fuel.
