And I just got back from the frozen Rockies! I spent the last week in Yellowstone where I experienced 37 degrees below zero (farenheit) and loved every minute of it. (And that doesn't include the wind chill factor.) Trying to fire up that snowmobile at that temp was soooooooo much fun. Took many a pull and got all warmed up in doing so. Anyone who thinks snowmobiling is an easy sport, doesn't know how to do it!
