That's very cool. The local short track, Cajon Speedway, used to host two 150 lap enduro events a year with up to 100 cars starting on a 3/8 mile oval. Talk about exciting!
They'd run 75 laps in one direction, take a 15 minute break and then run 75 in the other direction, with no yellow flags - only green or red. If a car broke down on the track, he just sat there and prayed no one ran into him. I saw the hardest hit I've ever personally seen in the last one. A guy lost his brakes going into a turn and ran straight into the wall doing about 60 mph. It took the track crew 20 minutes to cut him out of the car - but he was OK.
Sadly, the track was on land leased from the county next to a general aviation airport. The lease ran out in 2003 and the county wouldn't renew it, intending to use the land for airport expansion. Today, the land still sits, cleared out and vacant.
