In the early 1900s, Corona was known for its citrus, and even dubbed " The World's Lemon Capitol." Legend has it that Corona was laid out to resemble a wagon wheel with Grand Boulevard as the rim. This circular street is still probably one of the most unusual thoroughfares in the world, and from 1913 to 1916 it was even used as a racetrack. Join Huell Howser as he steps back in time to recreate the Corona Road Races complete with vintage race cars and even an attendee from the 1916 race.
