Tonight on the long ride home from dropping off a forgotten Christmas present at my mom's house, I nearly ran over a cyclist. He was what's commonly referred to as a bike ninja. Now I realize some people ride bikes not by choice but by necessity and bike lights can be expensive. But when there's a dollar store on every corner selling red and white leds for a buck there's no excuse for being a bike ninja. A couple of years ago on the ride to work I stopped a bike ninja and gave him my spare blinky, so starting next week I'm going to keep a small stash of dollar store leds on me at all times to help vanquish the world of bike ninjas.
