Harumph! Back during the war...young whippersnappers don't know....

Well, really, back during the Vietnam War the US Army started issuing plastic 1-leter canteens -- they were quieter than the aluminum ones used before, and when a little noise can mean your life, well.... Anyway, I have one from that period. I use it. It works. I don't notice any off flavors to the water unless they were there when I filled it.

The canteens are still issued, along with a two liter model. Out here in high desert country lots of people use two-liter plastic backpack type canteens (Platypus is one such name, Camel another).

I have a suspicion that we're a lot tougher than we give ourselves credit for being. If we weren't the whole damned human race would have died out long ago.

I figure that I'll just keep reusing the plastic bottles until they become so gross I toss 'em.
