Did something or other to my knee last Sunday so I took most of the week off riding. Felt good today. Cool. It was 54F this morning around 8:00 AM. I think it was around 64F or so during my ride. I caused a cyclist to crash. As I was coming up on two upright cyclists in front of me the lead glanced back and saw me, did a double take and cranked his head around even more and promptly ran off the right edge of the road and did a partial endo over his handlebars. I looped back to check on him and was concerned because he was really slow getting up. Cool guy. Great sense of humor. As I pulled up and asked him if he was OK he said he was and then said, “That thing is awesome. It really stops traffic!” I said “Yeah, but usually not so abruptly.” 😂 He asked for directions to Kensington which I provided and then we all resumed riding.
