Birds eye view of the 2012 San Antonio Livestock Show and Rodeo in progress. Notice that the entire parking lot is full around the AT&T Center, and Freeman Coliseum (Silver oval building). A Carnival, complete with rides, is occurring in the bottom left corner of the parking lot. The large buildings to the North are animal stables and barns for livestock. If you Zoom in too closely, in Google Maps, the image will change and the Rodeo will disappear. It's best viewed from a higher altitude.
