Trivia: Director Rob Reiner makes a cameo as the helicopter pilot helping Buster search for Paul's car.
Trivia: When Kathy Bates picked up her Oscar and made her speech, one thing she earnestly said was, "I'd like to publicly apologize to James Caan for the ankles."
Trivia: In the book Annie kills the young cop with her lawnmower. It was left out of the movie because the director didn't want the audience to hate the actress Kathy Bates, which is also why he had her use a sledgehammer instead of cutting off his feet.
Answer: According to the book, she goes to what she calls her "laughing place", itself a reference to the Disney movie "Song of the South", in which Brer Rabbit sings about having a "laughing place" where he goes when he's feeling blue, to cheer himself up. We can presume Annie has some cabin or clearing in the woods where she has made her own "laughing place."
