About 20 miles into my B'day ride yesterday (62, thank you) I was cycling along on what passes for a country road around here when I heard what was clearly a large dog start barking behind me. Not a problem, it was quite a distance behind me. Except...it was getting louder and louder and closer and closer at an unbelievably fast rate. My split second thought was that "I am a dead man. That sucker is MOTIVATED, and there is no way I'm going to outrun it." As soon as I started cranking at my max, a Prius with a very vocal Rottweiler sticking its head out the window passed me by. The dog was clearly having a great day, and in a few minutes my heart rate subsided to normal. I am rethinking electric cars.
