Winning the Daytona 500: "Just a cool feeling"

Matt Kenseth said "it's kind of sinking in," that he won NASCAR's Daytona 500 early Tuesday morning.

Kenseth won the first postponed Daytona 500 by holding off Dale Earnhardt Jr. and Roush Fenway Racing teammate Greg Biffle. The race was scheduled to begin Sunday afternoon, but was postponed because of rain.

"Daytona's the biggest stock car race of the world," Kenseth said on "CBS This Morning." "As a kid, being somebody that dreams of stock car racing, you always dreamed of the Daytona 500."

"To be able to win this race twice is hard to put into words," Kenseth added. It's just a cool feeling."

As a kid in Wisconsin, Kenseth said Daytona was a race they used to watch on TV. "It seemed like a whole different world away, and (I) always dreamed of someday running in that race. And never thought that would ever really happen."

Kenseth said his calm and cool personality is "about the same" inside and outside the car. "Yesterday, my radio quit working - that was extremely frustrating - and I was doing a lot of yelling in the car. So I'm glad they couldn't hear me for a while. Not let the highs get too high and not let the lows get too low. Just keep your head down and keep trying to accomplish your goal of winning races."
