What would you recommend - Mainstay or Datrex rations? I've tasted the Daytrex - interesting sugar cane/coconut flavour, less sodium than Mainstay. Or perhaps a MRE/IMP ration with a heater? I live in Canada and a frozen MRE/IMP just doesn't cut it in the winter. Most common winter survival problem is to have vehicle problems and stuck on a loney road for overnight - the intent of rations would be as a psychological pickme up and create internal body heat.
