A smaller, presumably less drunken version of the controversial Critical Mass bike rides,
Critical Lass—which launched in Chicago this summer—is open to women and trans cyclists of all ages (children who ride in bike seats or can maintain a ten-mile-per-hour pace are welcome). This month's Halloween ride will cover five to eight miles of the city and end at a restaurant or bar; a map will be posted on
massup.us for riders who want to join later. Meet at the Polish Triangle (Division, Ashland, and Milwaukee).
