Bike commuting will take a real hit this week for most of us East Coasters. We got mostly sleet in my city, which is slow to melt in areas where roads are shaded and north-facing slopes. I drove to work this morning and the major roads were in good shape, but I waited until temperatures rose above freezing and much of the black ice had time to melt. Neighborhood streets and back roads still have lots of frozen sleet and black ice. Hopefully the sun and temps in the 40s and 50s will melt much of the remaining ice today, and more importantly I hope that temperatures will remain above freezing overnight. If we get another hard freeze tonight, it could be several more days before I am able to ride.
