Last time I tried that was a "Steve Johnsons" up in Indy after a Dome race. They had what they called a fat man Kart set up and geared for us special kind of people. I was beating "Tony Stewart" for the first four laps of the race, he just couldn't get around me. Then they blacked flaged me for "RED FACE" flagman said it looked like I was going to have a heart attack. I think Adam Stiles later spun "Tony"
and went on to win the race. (True Story)
If they ever invent a "fat man kart with oxygen" I may think about coming out of retirement again.
