When I was involved as a car owner at our local 1/4 dirt track we feasted on passing points. Won 4 overall championship on 2 tracks. We would take bets amongst crew as to what lap our driver would take the lead with and with out yellow flags. We had a fast car dash (4 cars) Heat winners Dash (4 cars) final heat with the 2-4 place cars in each heat 24 car main event and 24 car or less semi. 4 lap dashes, 10 lap heats 10 lap final heat 12 lap semi and 25 lap main. On Holidays we had 100 lap open compition. with dashes and heat races. Super Modifies, Sprint cars, unlimited engines, fuel and wings, fast cars start in front. yellow flag laps count until 5 to go. No green white checker. Out here pavement was for road racers and the drags. Only one good 1/4 paved track was in San Jose, everything else was Dirt. Now there are very few track in California most put out of business because of noise restriction, tree huggers and high land values.
