There was a charity event at Lime Rock and my friend Liam rode in the passenger seat with Jeff Gordon and his teammate, because they'd never been to Lime Rock. https://www.youtube.com/watch?v=mzEy41Q0Nj4 I'm not sure if I mentioned Liam in these forums before. He's a member of our car club http://www.cartct.com/, and he's extremely talented. He's also a US Marine and he lost a leg after he stepped on an IED in Afghanistan in 2011. Two of our track days were covered by the local TV news and newspapers because he was able to get back to racing very quickly after losing his leg. As you can imagine, a guy with his talent and his story gets a lot of opportunities because it makes great PR. He races professionally now and won his second race. At one race, he matched Randy Pobst's qualifying time. He's also been interviewed on TV by Darrell Waltrip a couple times. https://www.youtube.com/watch?v=MmLBK3hUmaA The only special equipment that he has is a device that connects his prosthetic leg to the clutch pedal. Of course it has some sort of quick release mechanism in case he has to exit the car in an emergency.
