It is 8 a.m. on a cold Monday in New England. You're driving to your job in Boston, Massachusetts. The traffic has been mostly tame for the time, but minutes After you cross the Neponset Bridge And find the ENTERING Boston sign the traffic becomes slow as 5 MPH. All cars on the north bound are slow, and you can only see snow, cars, exit ramps and the skyscrapers of Boston in the distance.
