Once in the cold north of a November morning at Desolation Bay of Kluane Lake in Yukon Territory on the Alaskan Highway, I drove off after -33 degrees woke us up in the middle of the night and caused me to think perhaps a 20 lb LPG canister swap was in order for the camper. It wasn't. Of course in my frozen stupor I left the "empty" on the 20' enclosed cargo trailer tongue platform and would secure it before departure right? About five miles down the snow packed and relatively bumpy road I remembered and pulled over to check. There it was, still sitting on the tongue platform fat, dumb and happy.
