For this game, you need paper and pencil, and a score keeper. You can count cars of a certain make, or color, or whatever. For instance, you could count Volkswagons, or pick-up trucks, or cars pulling a trailer, or red cars. Each car can only be counted once - whoever spots it first gets it! You can either set a time limit to the game, or whoever gets to a certain number (like 20 cars) first wins.
