Weather in Calgary this weekend is supposed to be reasonable; no rain or snow, temperatures 0-15 C, light wind. I'll have my medium jacket and my Croix de Candlestick stocking cap. I went looking for my gloves this evening, and could not find them in any of the places I would expect them to be. It's not like I need them very often, after all. I think it's possible I left them in Oregon with my heavy winter-weight coat, as I'm more likely to need the coat and gloves there.
Rather than turn the apartment upside-down looking for a pair of gloves that has a good chance of not being there, I will just go buy a new set tomorrow morning before heading to BART to catch a train to the airport.
