Powder Springs resident since '95 here. Hopefully not for too much longer, God willing.
Good advice about living north of Macland in the post above.
I, however, don't live north of Macland. Hence my what I shall write below:
Better advice about just trying to suck up the commute and stay put out in Temple.
The PS area and Cobb in general have changed A LOT in the last decade and NOT for the better, IMHO. While the area up between Macland and Dallas Hwy is still nice, it's pretty expensive and the drive to FIB is no prize either . And with the rate of new development happening up that way, it's only a matter of time until the same ATL rot that ate up South Cobb washes over that area, too.
If I had it to do over again, I'd trade time in the truck stuck in traffic on I-20 listening to books on tape or learning Hungarian rather than grind my teeth to a nub watching a once-quiet suburb become just another ATL trash heap.
