That picture was only a little dusting of snow... I have ridden up this hill on many occasions (in good weather) and the other day people actually thought they could drive up it... the grade tops out at something like 18 %.

Traffic came to a standstill, the highways were closed, fligths were cancelled, and most notable was the fact Sixty wasn't out there riding his bike... save to go to his shop which is only a mile away... and that took half an hour as it was more of a hike than a bike.
