Finished our annual nighttime 200K brevet about 1:00 this am. Highlight was getting surprised by the couple monster truck tires lying in the shoulder. I managed to swerve off into the gravel but grabbed too much front brake and endovered. Landed on my shoulder, then the bike landed on me. Got up sore as hell but still in one piece, rode another three hours to the finish. Moral of the story, don't keep your headlamp on low just because you're cheap with batteries.
