 I grew up in Ohio, so I looked up where the towns were- admit it, so did you.  I also rate this episode 4 out of 5 invisible scones for Good. This story reminds me of other CBS Radio mysteries with a similar theme of being inside of a smaller version of something. IE: Town or Terrarium. Also that one episode of The Twilight Zone were the town the couple was in is fake... fake grass fake trees etc.. turned out it was a child's toy table with a model of a town... Good stuff very create and makes your minds eye really see it very vividly! Liked this one very much and I also remember it from a previous listening somewhere along the way.
