Good job, guys.
I did a chilly 57+ in southern Illinois (Madison County) on trails, saw the dedication of a new section near O'Fallon.... A bit of snow, a bit of ice.
Front tire (tubular) which was new in June, and went across Indiana on RAIN, flatted once, and it was basically too cold to add sealant and re-pump, so I figured I'd just run it up to high psi and move on. Then my brand new CO2 and inflator didn't work, so I borrowed a crusty one and topped her off with about 20 to go, did it again with about 8 to go, and the last mile or so, flat again. I got behind a guy who was OK with pulling, and sat as far back on the saddle as I could, and we hammered it home. I'll check it tomorrow, it's flat as a pancake now, of course, and I just don't feel like it.
