This time of year, every year, I begin riding in the dark again. And every year it catches me (and everyone else off guard). Last night, I had to reattach all my lights to my bike, my wife had to work her way back into feeling secure about me riding in pitch black and I had to re-familiarize myself with that somewhat eerie feeling of riding through remote farm country with limited vision. It's the same every year.
But, 'tis the season for relearning it all. Time changes really jack with my night (or pre-dawn) rides. Give me a couple more under my belt and it'll be second nature all over again... until next year, of course.
