THEATER: Tonight is the first preview night of Cal Shakes' production of Samual Beckett's Happy Days, directed by Jonathan Moscone. Beckett's astounding portrait of a woman buried up to her waist in sand explores the theme that "we are all alone in the face of death, and all alone in the face of life." Ticket availability for tonight's show is limited, so act fast!
