Coldest morning to date as far as I can recall, 3C/37F but clear and sunny. I wore a Buff folded as a beanie (

I ended up being too hot by the time I got to the coffee shop for a Pumpkin Spice muffin and an Americano so I stuffed the thick jersey in my pannier and was fine for the rest of the ride with just the baselayer and short-sleeved jersey (and Buff beanie and gloves). I wore shorts, no tights and I was comfortable on the legs too.
To the Canadians out there, Happy Thanksgiving Weekend, and to the rest of you, ha ha, you go to work on Monday, LOL (but have a great weekend anyway).
