In this Thursday, Aug. 2, 2012 photo, Nick Miller, left, and his sister Kendall Miller, center, from San Francisco, wear leotards in the colors of the United States national flag as they walk with a friend through Olympic Park at the 2012 Summer Olympics, in London. Patriotism and the games have always gone together, but gone are the days when one just waved a flag. Now flags are worn, seen all over London and especially at Olympic Park and other spots where the games are being played. (AP Photo/Ben Curtis)
