I think I've made a comment about not announcing on a pass once in my life, and it wasn't really about announcing. It was when a paceline decided to pass at a distance of about 8" when I was trying to move left to avoid potholes and crumbling pavement. Which I'm pretty sure that they saw, too. What I said was, "hey, you're riding me right into the potholes---give me another foot, at least".
