Theme: TO GRANDMOTHER'S HOUSE WE GO. Not necessarily over the river, but definitely through the woods, where we encounter THE BIG BAD WOLF in hot pursuit of LITTLE RED RIDING HOOD. Don't be alarmed if you had trouble finding them. The forest provides lots of hiding places. [Full disclosure: I had to get help from C. C. to spot them.] Lots of themage, and tight construction, as all of the WOLF's entries are the first words of two word answer, hugging the left margin, and our heroine's entries are the second words of two word answers, hugging the right margin. Note also that from top to bottom, our antagonist's and protagonist's answers alternate. Unusual placement for theme entries makes this a bit hard to suss, but high marks for creativity in executing this original theme.
