Took advantage of a fine weather day to ride this route again, traveling thru some of the Burden Hill Preserve. Going over the top (Coffin Hill) on unpaved Gravelly Road, while unclipped and going slowly, some sand took me down. Broke my fall with my right wrist but didn't hurt myself. And most importantly, I didn't get any sand on the chain. On Jericho Road, an older guy in a pickup, with a dog on his lap helping him drive, slowed and asked me if I was OK while I was stopped along the shoulder, rearranging my cue sheets. I thanked him for his kindness. The dog just wanted to get on down the road, looked like. At one point on a stretch of two-lane, in my helmet mirror I saw 3 dump trucks coming up from behind, while straight ahead I saw an oncoming vehicle and a narrow bridge. I signaled a right turn, then quickly bailed to a full stop on a driveway apron. Love my mirror. Solo, on the Spesh Roubaix.
