When I was a kid growing up, it was common to see vehicles from the outback with a square water bag suspended from a frame in front of the grill. The bag was canvas and leaked slightly--enough to keep the outside moist so that the contents would chill from the wind as the vehicle drove along. The water was nice and cold, just right for a hot summer's day. Oddly, I don't see them any more. Perhaps there are enough roadhouses along the highways that anyone can pull in and buy a chilled soft drink when they want.
