Regarding the $5.00 parking fee, you can buy a annual pass that is good for parking at all GA state parks, except Stone Mountain, for one year for $50.00 ($35.00 for us "highly experienced" citizens), from "Friends of Georgia State Parks & Historic Sites". There are also other benefits that come with the pass. See
friendsofgastateparks.org for details.
