On the ride in at noon it was almost 40F (4.4C) today! Only problem is on the ride home the melted snow has turned to a thin veneer of ice. My commute, which is a distance of 10 miles (16k), is almost directly west and thus inland and the temperature change is noticeable. I start the ride at the end of the Charles River where it empties into Boston Harbor and follow it inland. It's amazing how predictable the temperature change is whether I follow the bike path or take roads but as soon as I hit about 5-6 miles into the ride the ground temperature shifts and what were puddles in Boston are black ice in Brighton. The ocean keeps Boston a couple of degrees warmer at this time of year.

Am seriously considering some studded tires this year. I just don't think my chain stays will accomodate a tread width on anything wider than a 1.5. I'm not sure if anyone makes a 26x1.5 studded tire. Also managed to snap my front fender the other day when the temp dropped to about 0F (-17C) A stick that would normally have bounced off it cracked it in half like it was made of an egg shell.
