Before Dorothy meets the Scarecrow, she comes to the "T" in the roads. The "T" would have the top pointing to the the left making the roads like this: |-. Dorothy appears from the top of the "T" and approaches the cross. Over her left shoulder is the cornfield, with nothing there. In the next scene, she looks over her left shoulder again, and "POOF!!!" the scarecrow appears on the post. Where'd he come from?
