The wild flowers of 2011 are gone. The air is cool enough that no one thinks whether the spring is running. It doesn't matter. There is no risk that you will overheat. The debate is whether to start with headlamp, even at 7 AM. The days are shorter, the leafless trees and frost on the ground are evidence of the inevitable coming of winter. The clock is ticking, but there is still time for a few runs up high. Fortunately, the falling of the leaves is followed by the falling of snow, which makes way for an entirely different sort of run.
