Six Flags Over Georgia is now open for 2015! And to celebrate another season, for the first two months of the season, park attendees can ride Batman backwards. “We expect this season to be an incredible year for our guests,” Six Flags Atlanta Properties park president Dale Kaetzel said.” The season starts with Batman the ride backwards and also includes two new rides in the expanded Gotham City this May, the second season of our free water park, Hurricane Harbor, the largest Fright Fest ever and an expanded Holiday in the Park wintertime celebration.
