Six Flags Great America has been closed since November 2015. By the way, happy New Year Everybody! A group of my friends and I went to the border street of the park and got some footage from a Drone. This was back in December. Unfortunately I did not have my own camera with me at the time, I hope to get some stills soon. So here are the videos my friend Alex Sabatka took and posted on his channel.
The first is specified to an update on Justice League: Battle for Metropolis.
The second is a general overview of the park.
