This morning while driving along PCH through Malibu, I spotted a train of 8 cyclists up ahead going my direction. They were all kitted up (red and black was the theme) and hauling along in a nice line with the wind to their backs. As I passed in the far lane I gave them a few light horn taps. While waving so they knew it was a friendly gesture, I looked in the mirror and saw at least 4 of them wave back. That almost never happens. I don't expect anyone to take their hands off the cockpit in a tight group situation. I figure it was the perfect weather, the tailwind, and the less than normal traffic. Happiness is contagious.
