The Goods. You race, you get things besides contusions. 

You show up to watch or race, you get a SFVISBF button.

You complete any heat of any race, you get a race completed sticker to affix on your car. If you don't have a car and are borrowing a car, the sticker goes to the car, not the driver. One sticker per car per race set. 

You complete two separate races in different months, you get a driver t-shirt.

You win the first heat, you get to hold the winners trophy until next month.

You get last place on the first heat, you get to keep the skunk trophy until next month.
