wooly bear caterpillars are undulating slowly across sidewalks and bike paths everywhere, like rusty, pulsing bottle brushes. they refuse, despite our folk-wisdom attempts to employ them as barometers, to predict any weather at all. what they do quite reliably is to undulate slowly across sidewalks and bike paths, and, when prodded, to contract into bristly, rust-colored pillows.
