Warm weather (high 50s and low 60s) got me out on my longest ride in a while. I started after noon, so I rode about four hours in daylight and about 3 hours in dark. Scenery was good for both sections. I saw sunset colors over the Fruitlands view in Harvard, then full-moon-lit clouds after dark. I saw very little auto traffic. More pedestrian traffic than usual, with groups of jolly people out on the back roads walking around dusk. I saw no apparent drunk drivers, and no apparent open food stores or restaurants until nearing the end of the ride (Cumberland Farms in West Concord). I could smell Yangtze River restaurant as I approached Lexington Center near the end. Route was based on Harvard RSC 1720 ride, a Permanent by Pamela Blalock.
