So...I rode my bike to work today. This afternoon, I'm zipping across Georgia Ave in Silver Spring with the light (one of 3 major road crossings I have to make). I hit a bump in the road and hear something plastic-like hitting pavement. I look behind me and see my taillight skittering across the road. It bounced off the daisy chain on my panniers. I pull over, pondering how I'm going to safely retrieve it, when a big black SUV comes by and - CRUNCH - flattens it. I KNEW I should have taken that thing off for the summer. But, no! I HAD to leave it on... Blech...
