Just something we used to do. The cost of a bus for these types of trips is usually per hour charge because of the time the bus is used with a driver.We used to rent a 15 passenger van@130 dollars then remove one seat at home(very easily done usually the middle seat is a quick release system). Then elect a driver to and a driver from the event everyone just splits the cost. Plenty of room for coolers for livestock and refreshments. Mike
