Never quite went that far
Did the silk, polypro, chinesse drawers, field pant, USAF Fat Boy pants, same on top except got Eddie Baur down parkas to wear as we had to string com systems and such.
Trying to describe to someone (who has never had to *work* outdoors at -40 ) what "cold" means is tough. I can still remember how happy we were when a Chinook would blow in and the temps would rocket up to 0.
Or of people setting their tents on fire from running the Yukon stove full blast, trying to thaw out fuel so it would run, etc, etc.
Glad I live in the banana belt now - Anchorage.
Buddy of mine at NWTC caught his fart sack on fire - we beat it out with our e-tools. Never laughed so hard in my life.
