"For generations human teens have crept into pastures at night and tipped over defenseless cows in their sleep. "Last night they tipped the wrong cow... Elsa was the prettiest in the pasture, and Clyde the Bull was in love. "Seeking revenge, this morning Clyde rushed onto a nearby highway, causing an auto accident and stopping traffic for miles. Now he's organizing gangs of cows from the pasture to tip cars off the road. "Watch out world, it's the cows doing the tipping now!" Collect gangs of cows by drawing cards from the draw pile or your neighbors' discard piles. Use these gangs to tip over the 5 types of vehicle cards in 5 different colors. Your score is based on the set of vehicle cards you tip; Busses are worth more than Cars and Trucks, but they also require a bigger gang to tip over. Motorcycles aren't worth as much, but they're easier to tip (require a smaller gang). You score for collecting types of vehicles as well as for collecting colors, so you can go for a bunch of Tractors, or you could try to collect all the Blue vehicles.
