Alex Melinkoff's mother could have given him powdered skim milk during his visit to Peru. I put cup of the stuff in a small plastic bag and use one a day, mixing it with cold potable water, so I can have that pleasure away from home. Hotels have safe bottled water available. As the bulk of the milk supply decreases, I have space for purchases, too. I also take dried fruit for snacks.
