And you don't remember how to get there???
From Gwinnett Place Mall, you take 85S to Exit 101 (Indian Trail Rd), Go left across the bridge towards Lilburn, 4 miles or so to a right onto Hwy 29/Lawrenceville Hwy, about 1-1.5 miles and the shop is on the right just before Rockbridge road right next to a diner called "Judy's Diner".
I can't remember what mount and balance charge is, but you can call the shop and they'll tell ya. I think it's $21/tire, but don't quote me on that.
