Joe DiPietro's Over the River & Through the Woods is a charming stage sitcom, and based on a final dress rehearsal held January 10, the production of it that opened the Playcrafters Barn Theatre's 2006 season is perfectly charming, too. The large, invited audience of (mostly) seniors who attended the rehearsal seemed to have a terrific time; the show's punchlines, more often than not, got their laughs, and there was no denying the sweetness of spirit that emanated from the show - if smiles were audible, it would have been deafening in the Barn Theatre.
