I thought the saying was that "an army travels on it's stomache." Go without food??
Even with the armys rosetta stone you'll want this bookI(I'm working on it too, but I had to pay $500 for my program). It's only a few bucks and you'll se just how good it's set up. Tell you what, IF you buy it and don't use it while in Ukraine I'll buy it back from you after you get back IF you can look me in the eye and say it's not worth it! No Schitt!
