I packed up the bike with sleeping bag & pad, since I hadn’t slept outside in… I can’t remember, which made me sad. It was -15F when I left my cabin, so I brought my -20F bag, as it was snowing and clouded over, which should have meant that it was to get warmer over the course of the night. Well, I woke up after 9.5 hours of sleep to clear skies and at least -25F.
