The free shuttle from Atlantic Station has been started again. I used it last week and it was a little slow, but, they are adding another bus and personnel to manage the departures. Two years ago the shuttle was run using the Tech Trolleys, now Atlantic Station is providing the buses (they are super comfortable and air conditioned, and hold more people). They leave from the street in front of the Regal Theaters and drop you off at 3rd street and Spring street at the I-75 tunnel about 2 blocks from the Varsity. It only cost me $6 for the Mercer game versus the $20 parking lot I've been parking. Another thing I like about it is you have easy access to I-75. Try it you'll like it.......
