In the back of any Richmond Hill Barn Theatre program, you'll find a chronological listing of which shows have been produced at the theatre over its past 40 seasons. And while this catalog of titles is nothing if not varied, the assorted comedies, dramas, thrillers, and such do share a common link: Not one of these plays is one you'd feel compelled to attend with young kids in tow. (The Barn did house the holiday comedy The Best Christmas Pageant Ever in 2007, but that was a bonus offering added to the venue's annual six-show lineup and isn't mentioned in the program's inventory.)
