The museum is hosting “A Stake in the Ground: 1774,” a show made of three 20-minute, site-specific plays produced by Boston-based theater company, Plays in Place. “Some of the research in the playwriting turned up ideas that sort of challenge what we might think of as what New Englanders were like in 1774,” Sloane said. The third play, “Sparks on Dry Tinder” by Patrick Gabridge, comes after the Liberty Pole has already been established. This show takes place near a replica Liberty Pole that stands where the original one once stood in Deerfield centuries ago. Sloane and Kingston both used the phrase “unflattening history” to describe the work that Plays in Place does.
