Las Vegas Motor Speedway
On October 16, 2011, the final race of the 2011 IndyCar season, the IZOD IndyCar World Championship, was held at Las Vegas. However, the race was halted by a horrific crash on lap 11 that involved 15 cars, some of which became airborne, and some of which burst into flames. The crash began when Wade Cunningham made light contact with James Hinchcliffe, but the situation turned into a big pile-up of cars. The crash allowed a red flag to be waved almost instantly, due to the remains of the damaged cars and the amount of debris on the track.

Wizard World Chicago Comic Con, commonly known as the Chicago Comicon, is a comic book convention held during the summer in Rosemont, Illinois, United States, at the Donald E. Stephens Convention Center. It was traditionally a three-day event (Friday through Sunday), but in 2006, it expanded to four days (Thursday through Sunday). It was founded in 1972 as Nostalgia '72, Chicago Comic Con and later as the Chicago Comic and Nostalgia Convention by a local dealer (and school teacher) named Nancy Warner.
