Maybe he said, "slow down" not "mow down." Or maybe I heard him wrong entirely. I will never know.

There aren't many dark spots on that route, and they aren't big. They're worse above 100th St but still not awful. I agree that bright headlights on bikes are extreme overkill there. They're pretty inconsiderate, and they seem mindless to me. And I see other weird stuff, like a red light in front and a white light in back. I don't think these people are thinking.
