So if anyone else comments that "It's too cold for a Holiday event at **insert park here** and refuses to subscribe to the idea that people are used to the seasonal averages wherever they live and don't care then direct them to this video that someone shot of Great America last night when the temperatures were hovering around the high teens / low 20's. The place is packed given the conditions.
Note: Raging Bull running in those conditions at the 19 second mark because Six Flags is awesome.
