Our limited exposure to the outskirts of Sandy (winds up to 60km/h, light but driving rain) was over yesterday. Today's ride was in 2C, light rain, 21km/h N wind so I was comfortably cool with a bit of dampness on my legs through my tights and a bit on my lower back where my coat ended.
I didn't dress up but my (too late) idea was to get a skull balaclava for the ride in and then wear my mostly black biking outfit as my costume. I didn't have enough time to buy it so maybe I'll get it for next year.
