The Brickyard 400 began in 1994 and has since become the sport's most-attended event, drawing nearly 250,000 spectators to the inaugural race. The Brickyard 400 made history in 1994 at the Indianapolis Motor Speedway as the only race to be run at the famous track other than the Indianapolis 500. The event takes its name from the 1-yard stretch of bricks that run along the start/finish line of the track, and they are the last bricks that remain from the track's original brick pavement that was laid down in 1909. With NASCAR fully in the fold at the Indianapolis Motor Speedway, drivers have embraced the tradition of kissing the bricks with their pit crews after taking the checkered flag. These kinds of unique moments hearken back to the early days of American auto racing and showcase just how intertwined NASCAR and stock car racing have been in the growth and popularity of the sport.
