I went to this last year and it was awesome. Lots of buses showed up to camp, plus even more VWs. They showed a double feature too! Tiger, GA is only about 45 minutes from Helen, GA.

Me and Hippie (in the orange bus) met up at the Coker cruise-in and made the trip down to Tiger for the campout. About 20 other VW buses were there and we got there right before dusk, when the movies started. Being that we drove the furthest distance, we got free t-shirts! The movies were Dolphin Tale 2 and If I Stay, neither of which were particularly interesting but we had a great time nonetheless.
