Stone Mtn. is a really big place.... Pets are probably not allowed on the Laser show field because people sit on the ground and no one wants to sit in any messes. Other than that there are a good many other places where pets are allowed parking is right next to these areas and there are picnic tables and grills some areas are shady and some places are out in the open...... hope this helps some too.
It could be a henderence if anyone wanted to hike up the mtn. or go inside to see the memorials, but it could be cool if we just wanted to sit outside and chat..........
