Crackers: forgotten but found

BBC News reports today, and Reuters yesterday, on the discovery under Brooklyn Bridge of a stash dating back forty years of "350,000 Civil Defense All Purpose Survival Crackers, medical kits and now-empty water drums."

Apart from prompting a string of "remember what the Cold War was like?" reveries, was anyone concerned that emergency supplies were so easily forgotten about?

And why on earth would its location still be considered secret (or have they simply already let this information slip from their minds again)?
