We will still have the same point structure as before but will not use this system to invert cars by average for line up purposes. A Champion will be awarded but the money will be put into the purse weekly not paid out at the end of the year. A $10 entry fee will be collected for every late model entering the gate each night. $50 of that money will go on the top of the purse. The winner of that night’s feature will draw a spoon on the front stretch. There will be as many spoons in the jar as cars starting the feature (including the number 1). The number that is drawn will award the driver that finished in that position a $100 bonus for the night. There will be no annual registration fees for Late Models.
