Alliance Repertory Theatre returns with its production of Paula Vogel’s The Oldest Profession. The comedy focuses on five “working girls”—the youngest being 72—who are coming to the end of their long careers. As they wait for appointments, they reminisce about their early years and argue about their career options today. Performances are 7:30 p.m. July 23-24, Aug. 27-28 and 2 p.m. Aug. 29 at Valhalla Boathouse Theater at the Tahoe Tallac Historic Site, three miles north of South Lake Tahoe on Highway 89. Tickets are $15-$17. Call (888) 632-5859.
