Saturday is a festive day in Morningside Park thanks to the all-ages Common Ground Festival. The revelry climaxes after dark with Morningside Lights, an illuminated parade that provides an opportunity for musicians and other costumed performers to lead revelers in taking back the night. You can simply view it view or sign up to participate as a lantern carrier. (Rehearsal and line-up for lantern carriers begins at 7pm in the park at 120th Street and Morningside Avenue.)
