The upcoming Grove Players production, “Over the River and Through the Woods,” is about love, among other things. The love in this story is familial rather than romantic, as the story is about a young man, Nick Cristano, who is in his 30s, and his two sets of grandparents, Frank and Aida Gianelli, and Nunzio and Emma Cristano, who are in their 70s and 80s.
