Galeen Roe decides to see all of Suzan-Lori Parks’ nationwide theater festival “365 Plays/365 Days,” in which more than 600 theaters in Los Angeles, Atlanta, San Francisco, Washington, Chicago, Minneapolis and other participating cities committed, sight unseen, to presenting one week of Parks’ date-specific works. So Parks wrote a play dedicated to Roe: “I think this will actually perfect the cosmic juju thing, to sort of write a play to the perfect witness, an audience member.”
