Forgot to charge my light the night before, but luckily I didn't have to use it until the last mile of my commute home. I ran into a stranger on the trail who was very friendly, so I drafted him for about 3 miles (people like that make my day!). We were crusing along at a consistant 22/23 mph.... schweet! Wish I could push myself when I'm riding alone, but it's easier to chase someone and try to keep up.
