Exterior Environment #4: Signage use

I took a picture of this sign because it depicts how “set” things are at Stone Mountain. Trails are very neatly cut out and signs surround them warning the users of the dangers and (sometimes) fees they may receive for going off the trail. In a way, when you think about it, is all of the park really open to the general public? Or are we limited to certain areas within the park and being excluded from what lies off the trails?
