Do not (i.e., do not) look at the weather before you go out running. I had prepared myself mentally for temperatures in the twenties. I was ready for it.
I definitely was not ready to go running in 6°F weather. I almost went back to bed, but then I realized I'd be like the Monkey brothers from Colorado whining about the cold weather. Taking a deep breath, I burst from my dorm and plunged into the dark, frigid morning.
Five miles later, I had seen only five species: Northern Cardinal, American Crow, Slate-colored Junco, Black-capped Chickadee, and Downy Woodpecker. All were new except for the corvid. Eighty-seven!
Next time, I'm not even checking the weather.
