Beautiful, sunny, chilly Halloween afternoon and 500 kids with their teachers costume-parade around the school block and then gather in the courtyard for a flash mob “Ghostbusters” performance.

My favorite of course was Laura (Harper) Ingalls in her bonnet and long pink dress. Another favorite is Harper’s good friend Sylvia, with her pink cowgirl hat. Other family/friend onlookers were Auntie Jane, Grandpa Whitey, Jenny and Case (Sylvia’s mom and dad), and Andrea, the Viking-horned German intern who is living with Jenny and Case this school year (horns apparently borrowed from EEK).
