Modern technology has not eliminated the need for such strategies. Some years ago, I heard four young women talk about a winter dog sled trip starting in Winnipeg, going through Great Bear and Great Slave Lakes, East to Hudson Bay and then South ending at Churchill. They said they had to keep their GPS units warm inside their clothes except for brief looks otherwise the LCD screens would not function. As I remember the high temperature for the first month of their trip was -30F. They did stop in native villages and were air supplied. One big problem was transferring gasoline from tins to stoves as a few drops on skin meant instant frost bite. --~--~---------~--~----~------------~-------~--~----~ NavList message boards: www.fer3.com/arc Or post by email to: NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
