Welcome, neighbor! Here are 2 locations of BBQ Galore, not too convenient for you, though:
# ATLANTA (6.8 mi. from 30062)
6550 Roswell Rd.
Atlanta, GA 30328
404-255-2665
# ALPHARETTA (13 mi.)
5530 Windward Pkwy.
Suite E 400
Alpharetta, GA 30004
678-459-1950
If these are not convenient, you might try Home Depot or Lowe's, or hardware stores - anyone who sells grills. Most of them will at least carry hickory, popular in the South and probably another choice (apple is always good).
