Last night was like that. Dinner out with Ellen, then, on the way back to the parking garage, a thought: Why not a quick walk on the W&OD Trail, a 45-mile ribbon of asphalt from the D.C. suburbs to the foot of the Blue Ridge. It’s easy to reach from Reston Town Center, and, as it turned out, only a few steps from my car. 

It was 8:40 when I started, but the light that seemed abundant when I began drained quickly as I walked  first west then east. The W&OD closes at dusk, but that meant nothing to long-distance bikers with their powerful headlamps, or to the rest of us, either, who sauntered at a twilight pace.  It was good to walk through the gloaming.
