I lived at 9000' with sideways wind that would knock you down on the ice, wind chill well below freezing, Bronco II entombed in snow and ice from the previous day of snow bashing....pry the frozen drivers door open, crack your feet on the frozen lake that is the drivers floor mat, insert key and turn......vroom starts up just like the day it was installed
