2nd commute on the winter beater MTB. Weather was 25F, no precipitation. Left home, got far enough away to get warmed up (maybe 2 miles) and realized I forgot the pump!

It was beyond my "normal" point-of-no-return, but on a 25+ mile (one-way) commute I figured Murphy's Law held more sway than probabilty would allow... so back I go for the pump. Dropped a jersey at home since I was already sweating.
Total commute time: 2 hours 40 minutes, including forgot-the-pump-house-whipped. Total distance (est-no computer on this bike yet): 25 miles + go back for the pump (2?) + (MUP distance > driving distance).
My two new cold weather commuting favorites are work-provided dorky looking clear wrap around over-the-eyeglasses safety glasses. Bingo, no more eye-wateringly cold wind in the eyes. The second is a pair of
Nashbar neoprene gloves (and poly liners). Windproof and warm, despite getting too sweaty.
