need a big group and two cars but:
two teams. each team has a driver, “copilot” and 2-3 “hostages”. hostages are in the back of the car blindfolded. the cars start at the same place and have a certain amount of time to drive as far away as they can (15-20 min?). they then drop off the hostages, who take off their blindfolds, and call the other driver/copilot. you can’t use maps, but you have to explain to the driver where you are so the driver can come get you. whoever makes it back to the original starting place with the hostages wins.
