KURT BUSCH SAYS SINCE MARTINSVILLE SPEEDWAY STARTED HOLDING NASCAR RACES IN THE LATE 1940's, THE REASONS A DRIVER DOESN'T MAKE IT ACROSS THE FINISH LINE HAVE CHANGED...

(WHEN THE TRACK WAS BUILT, IT INITIALLY CHALLENGED THE CARS TO SURVIVE FOR FIVE HUNDRED LAPS. NOW IT'S MORE ABOUT THE DRIVERS STAYING FOCUSED AND WHAT THEY CAN DO TO BEAT THE NEXT GUY.)

AND WHAT DOES KASEY KAHNE THINK ABOUT THIS HALF MILE  TRACK?

(I LIKE MARTINSVILLE, I THINK EVERYBODY DOES, IT'S DIFFERENT. SO IT'S NICE TO GO TO THOSE TYPES OF TRACKS  ONCE IN AWHILE AND SWITCH IT UP.)

A BIG WEEKEND FOR MARK MARTIN AT MARTINSVILLE, AS HE BECOMES  ONLY THE EIGHTH DRIVER IN NASCAR SPRINT CUP SERIES HISTORY TO START  EIGHT HUNDRED RACES.

AND GREG BIFFLE SAYS HE'S NOT LOOKING TO JUMP SHIP THANKS TO A COMBINATION OF THE ECONOMY, CURRENT DRIVER LINEUPS AND THE IMPROVEMENT AT ROUSH FENWAY RACING -- HE'S CLOSE TO SIGNING AN EXTENSION WITH ROUSH FENWAY RACING TO CONTINUE DRIVING THE NUMBER SIXTEEN FORD.
