A lesson on post crash inspection

Lap # 2 of Quadcross, my wheel slid out in a turn and I crashed fairly hard, moving myself from nearly last to dead last. I checked the the hoods were still straight and hopped back on. Only to hop back off again when I realized that the chain had come off. After getting up a good amount of speed, I crashed again in the next corner. Clearly, there was a problem with the bike and it didn't take to long to find a completely flat front tire. A little attention to detail after crash # 1 would have been smart. Fortunately, bruises and road rash were the extent of injuries from that day.
