I like Adventure Outdoors. They have a HUGE selection.
-Get on I-75, head north west of the downtown ATL.
-Continue a few miles on I-75 until after you get outside the I-285 loop.
-Still on I-75, start watching for a "Windy Hill" exit.
-Get off on Windy Hill, turn left (heading south) going over I-75.
-Continue on Windy Hill for 4 or 5 miles. You will get to a major intersection of Windy Hill and South Cobb Drive.
-Turn right onto South Cobb, and almost immediately you will see a long white one story building on the right side.
-That is Adventure Outdoors.
