Catching up from yesterday -
Coldest day I rode in (~18 F), but found I had enough layers to keep me warm, with the exception of the tips of my fingers and toes. Went for a drink after 40 mins, water bottle was half frozen!
Ride home was really nice too, only two bikers, one a guy commuting home with a kid in a Burley d'Lite. Probably the nicest round trip I had commuting in a while, which surprised me due to the weather.
