It was a lot of fun. I rode 10 miles. The weather was nice and there wasn't much traffic. My goal was to find a bike trail that I've heard of, but having never ridden it, it was too dark to find the entrance (it's behind some bushes, and I only knew vaguely where to look). Even though I didn't find the trail, I took a nice leisurely ride around town.
Going 15mph at night feels more like 30. Familiar territory takes on a whole new feel. It's an exciting experience.
I had ample lighting, and I had no trouble seeing obstacles in the road. Drivers had no problem seeing me, and they were extra courteous, switching lanes to pass me rather than zipping by a foot away from me. I did have one car honk at me, but that's to be expected.
Anyway, I just wanted to share my experience, and my new love for night riding.
