For many years, Anheuser Busch (and other bottling companies) have canned water & shipped them to places that had a disaster - and it has been one of my "pet" collection, here is a page dedicated to them:
That page hasn't been updated since 2002... WHICH was about the time I thought they stopped making the cans since bottled water was starting to be more popular, and the plastic bottles were used more then cans (at least that is what I thought.)
But anyway, looks like A-B has made a little more then a million cans and shipped to the North-East.
I've collected cans for many years - run the (very outdated) popcan.org website. I've once wanted forums & a site like this - glad to see this one here, and plan to support it as much as possible. ***UPDATE*** I May be trading soon! My Collection will finally have a home!
