Is 1640 AM a Six Flags station as well? Because I just questioned my dad about it, and he is saying that's what he remembers. Maybe there is a second station?
Maybe 1640 AM is a forgotten station that hasn't been updated since 2009, advertising "Amazing and exciting coasters, such as The Chiller, Kingda Ka, and the Great American Scream Machine! And don't forget to take your kids to our kiddie areas, including Bugs Bunny National Park and Balin's Jungleland!"
