The Circa '21 Dinner Playhouse's Jack Frost Saves Christmas is the most adorable children's play I've ever seen. Okay, it's also the only children's play I've seen since... well, since I was a child. Still, it brought out the kid in me as I danced and sang along - at the appropriate, invited times, of course - and I wasn't alone; the children in attendance at Saturday's performance, including the two I brought along with me, laughed and danced and shouted exclamations of delight at the play's proceedings.
