canvas water bag
traveling around Australia with family of 6 in a old dodge with camping gear, huge army tent with poles piled high on the top of car us four kids in the back
mum cooking damper in the open fire to have with stew sleeping at night without a worry because dad was outside sleeping by the fire on the camp stretcher but my favorite was how fresh and cool the water was from the canvas water bag hanging on the front of car
not only did the air passing though cool; the water it also cooled the radiator
I have no idea how mum and dad did it they carried everything we needed and our ages were 2,5,7,9
best holiday ever
