The Long Wharf Theatre presents its seventh annual Discovery Day Saturday, Nov. 2, from 9 a.m. to noon. Children, ages 5 to 12, are invited to become detectives and help search for the missing Long Wharf property. As they search for the culprit and earn their detective badge, kids will get to experience a bit of the magic behind the theater and participate in an acting workshop with a Long Wharf artistic team member. Admission is pay-what-you-can. Information: 203-787-4282 and www.longwharf.org.
