Publix Marathon Terrible route design

The Publix GA marathon was a terrible burden on the community. The route essentially created a "no drive zone.". That in some cases meant you could not get out of the zone and in almost all cases you could not get in. I had to abandon my car and walk home. So did many others. As a loyal Publix customer I am deeply upset by what they put me thru. There should have been a better route design.
