I used to own some hobby aircraft, but I got rid of them. I didn't have the time.

I've been happy with my life. Also very lucky. I lead two lives - businessman and racer - and it feels like the best of both worlds.

New tracks like Las Vegas, hell, you could drive off the end of that track and continue safely 20 miles into the desert. But there's not a day goes by I don't think of Scott [Kalitta]. It's still traumatic.

I never thought of retiring. I'm a racer.

Many of our racetracks were built in the '60s - not much real estate for runoff.

I'm easy with employees. I make sure they get credit for their work. Naturally, sometimes a guy will screw up, and I'll have to apply some "retraining."
