@izzythepush,
He's not from an imaginary Ohio, he's from an imaginary Riverside, Iowa.

The place where the astronauts in "Martian Chronicles" took off from was in an imaginary Ohio.
Very good book, Martian Chronicles; Ray Bradbury also wrote Dandelion Wine, Illustrated Man, October County, Something Wicked This Way Comes, I Sing the Body Electric, R is for Rocket. All really well worth the reading. They are not "space" stories. Most of the chapters of his books can stand alone as beautiful short stories. I'll be on Amazon when I finish this.
Really if you would read Dandelion Wine or Martian Chronicles, you'd thank me for turning you onto them.
