Yesterday night, I was biking to a friend’s house on a small country road when I saw some blinking blue light over the hill. As I arrived at the top, I saw an ambulance, and between it and me, a large cow silhouette, a cow that had a "thou shall not pass" attitude. I faced her for a while, but the road was too tight to quickly run around with my bike, so I decided I would better retreat and take another road and let that one to the stroboscopic cow.
