The NASCAR Sprint Cup race at WGI just ended. There was a pretty spectacular crash on the straight between the Carousel (Turn 5) and what would be Turn 10. NASCAR doesn't use "the boot" section of track, so cars come wide out of the exit from turn 5, then flat out into turn 10. One of the cars went WAY wide on the exit, and, as he came back across the track, bumped the nose of a car behind him. That car bounced off the tires at the exit of Turn 9, spinning back onto the track into the middle of the pack, sending one of the other cars (literally) flying into the Armco at the inside of 9.
Nobody was hurt, but there was an impressive amount of damage to the cars and the barriers. The race was red flagged for over an hour while the Armco was re-built.
Though I'm not a big NASCAR fan, it was a pretty exciting race, especially the last few laps. The battle for first place went right down to the wire. Watching those big, heavy, fast cars playing "chicken" going into the bus stop was really fun to watch.
