With 100 days to go until the District of Columbia hosts its first major auto race.
The Cadillac Grand Prix is set for July 19-21 in the parking lot area outside RFK Stadium. Construction on a temporary 1.9-mile raceway has already begun. Organizers made several announcements Thursday, including details of daredevil Robbie Knievel's promised record-breaking stunt. He'll jump his motorcycle over 25 Cadillacs (the race's main sponsor), in honor of the 25th anniversary of Elvis Presley's death.
