I bought and MCI just to see how it was packaged, as it looked similar to the "C"-rations my father used to mention; this particular MCI looked identical to the one pictured on this site listed as from 1975...then I got curious, and opened the "B" unit, then more curious and I made myself a cup of hot cocoa to drink while I trimmed the Christmas tree...it was perfect! Then I got more curious and opened the "cinammon nut roll"...smelled good, really good, so I ate about a third...I felt fine in the morning, so I had the rest for breakfast at work, where I use a lot of MRE, British & Canadian rations. Never had a problem. O.K., even if this ration were from as late as 1980, that is still 26 years. I told a Vietnam vet friend to amuse him, and he wasn't even shocked about the age - as his unit was given surplus WWII rations in the 1960's prior to recieving the newer MCI's !! I don't know about the surplus "C" rations, but my MCI was yummy. (No I wasn't brave enough to try the Spaghetti)
Anyway, who has tried the oldest ration???

perhaps I should change it to irrational)
