I think the Nite B4 is running it 63rd annual race this year and the Little 500 is running it's 60th annual race. I went to the Nite B4 for years but they kept adding fendered divisions to the card and charged for parking. I made the switch to the Little 500 about 6 or 7 years ago and I will never go back to the Nite B4 again. One word describes the Little 500 - AWESOME!
