At this Moth StorySLAM, it’s your chance to get on stage and tell everyone your best “voyage” story. Don’t fret about whether your voyage was an epic trek across a continent, or an introspective voyage of your mind. It just has to make for an interesting story. If your story makes the cut, NPR’s “The Moth Radio Hour,” will broadcast it live. All you have to do is show up, sign up and have fun.
