Several years ago, on a cold, mid-March evening at about 10 p.m., I took my dogs out for a walk beyond the lights of our home in Carbondale, Colorado. The sky was ablaze with stars, and as I looked up for the Big Dipper and the North Star, I noticed that the far horizon pulsated in a green glow. I couldn't believe that I was seeing the northern lights.
Bearing witness to the aurora borealis in Maine and New England is one of the greatest yet most rarely seen spectacles for anyone willing to sacrifice a bit of sleep.
