I remember flying in to Saskatoon once for a one-day business meeting with a jacket like that, and the temperature was something like that. The walk from the hotel to the meeting site was about two blocks, and I felt like I was going to freeze to death.
When I walked in to the office I was just about turning blue and shivering in this pathetic spring overcoat. Without another word the receptionist picked up the phone and announced, “The gentleman from Toronto is here”. (At least she didn’t say "There’s a frostbitten idiot wearing a spring coat in 35-below weather that just walked in – it must be your guy from out East.)
