From the article: " . . He had been on a bike ride when he had the sudden feeling that something dangerous was nearby. " I sometimes wonder in the early morning light, if I will encounter something unexplainable during my rides.
I am amazed when I ride, some people sense before I am even close enough to announce that I'm behind them that I am there and look behind. Then there's the opposite; those that you practically have to yell to get their attention. My knobby tires do make some noise. I suppose some hear me coming.
