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.
Islamic Society of North America
ISNA holds an annual national convention, typically on the Labor Day weekend in early September, which is generally regarded as the largest annual gathering of American Muslims in the United States. In the last few years, it has been held most frequently in Chicago, Illinois. The convention features Islamic lectures, discussions, debates, nasheeds, and Muslim comedy. A notable comedian who has repeatedly performed at ISNA is Azhar Usman. In 2012, the ISNA Convention was held in Washington, D.C. Deputy U.S. Attorney General, Thomas Perez, addressed the 2012 Convention, and other prominent representatives of the White House have attended in the past, including Valerie Jarrett, President Obama's Senior Advisor for Engagement and International Affairs in 2009 and Homeland Security Secretary Jeh Johnson in 2016.
