With each successful jump, the public wanted him to jump one more car. On March 25, 1967, Knievel cleared 15 cars at Ascot Park in Gardena, California. Then he attempted the same jump on July 28, 1967, in Graham, Washington, where he had his next serious crash. Landing his cycle on the last vehicle, a panel truck, Knievel was thrown from his bike. This time he suffered a serious concussion. After a month, he recovered and returned to Graham on August 18 to finish the show; but the result was the same, only this time the injuries were more serious. Again coming up short, Knievel crashed, breaking his left wrist, right knee and two ribs.
