Dan, I would be interested if indeed they are going to be hard to come by. But,,,, I don't see the military switching to something that wouldn't be waterproof, crushproof,etc. And, if indeed they have solved those two problems with a new space age cardboard, wouldn't that mean there would be even more steel cans coming into the market because of military obselecence?? Or, I could be totally confused and dead wrong from thinking too hard? bob
