Lanford Wilson’s 1975 play The Mound Builders has set up camp at off-Broadway’s Pershing Square Signature Center, and on March 17, the stars celebrated their official opening night. The Mound Builders tells the story of a group of archeologists and their families who spend the summer in Illinois to uncover the mysteries of the Mound Builders, an ancient Native American civilization. After the suspenseful performance, stars Zachary Booth (Dr. Dan Loggins), Lisa Joyce (Dr. Jean Loggins), David Conrad (Profesor August Howe), Janie Brookshire (Cynthia Howe), Will Rogers (Chad Jasker), Rachel Resheff (Kirsten) and Danielle Skraastad (D.K. Eriksen) welcomed their friends to a starry party at the Pershing Square Signature Center.
