We had planned to do a lot of cooking out along the road and had taken along two picnic freeze boxes. We might just as well have one of them home and possibly the other as well for each time we stopped to cook out we had to unload the trunk -picnic basket-dishes-freezers-when we got thru dishes had to be washed-packed away and all back in the trunk of the car again. Don't think it was worth it and probably won't do it on the way home. The most important things were the two jugs. The half gallon jug was glass lined and did not hold the cold so well. This we would fill with ice cubes-put in two cans of frozen concentrated orang juice  and this they would feed during the course of the days trip. It would start to get warm about 2 PM and then we would dilute it with water from the gallon jug. The gallon jug was stone like a crock and kept cold much longer. The children preferred this to the orange juice, Periodically Helen and Gladys would wet a napkin and I would wash my face to keep me awake. They would also wash the top of my head and the back of my neck to keep me awake. These were indispensable.
