I was out east over the holidays and experienced my first sub zero temperatures in New Hampshire. It's really not too bad as long as the wind isn't blowing, you only go outdoors for 2 minutes or less, and you come back inside to a warm house and roaring fire
But then I also walked around Boston at night in 15 degree temps and 10-15mph winds and that felt MUCH colder.
Anyway I flew back into Oakland around 11pm last night and the balmy above-freezing weather felt pretty good
