In Stamford, CT I laugh at the polar vortex. Been riding 4x/week in 30 mile pre-dawn rides for the last four weeks. Lowest temperature was 6 degrees Fahrenheit. That was a little chilling on the hands going into the second hour but not too bad. Snow really has not been a problem as we had a few 6 inch drops but they were totally plowed out the next day.
Glad the cold spell is now past us and the warmer 18 degree + mornings begin tomorrow.
