The days are getting shorter.
I think every commute I've made recently has been either in Near Dark, Mostly Dark, or All Dark.
The abundance of this inky black cover, of course, means plenty more ninjas. I saw one tonight cruising through City Park: no lights, no helmet, no hands. Sitting straight up, looking the world straight in the eye, and just begging to be mowed down.
What a maroon.
On a different note, but related to lighting, when I see another well-lit cyclist (read: fellow pirate) coming at me down the path, I usually slip a few fingers over my lamp so I don't blind the poor guy. Not enough to douse the thing, rendering me invisible (read: dirty ninja), but enough so that he isn't shocked and awed by my passing.
I have yet to have this courtesy extended to me in return.
It's like driving down the road with your high-beams on, folks. Dim your lights for oncoming cyclists on those narrow bike paths. It's just the nice thing to do.
