No snow here in DC. It was 37 F / 3 C and very light rain. A pity, really -- even though I had swapped off the studded tires, I was hoping for one last snowstorm of the season.
The Schwalbe Marathon Plus tires provided a quiet, smooth ride. If they are as flat resistant as they are supposed to be, they could prove to be outstanding "non-winter" commuting tires.
