Our Fearless Director told the kids they could dress up (no scary costumes)
so some (most) did. She is "Sherlock". I think the Mad Hatter wins for Best
Costume. He had his own March Hare (but Spenser is not in my class this year
so I didn't get a picture of him alas!). There were a LOT of hippies. The
Sixties must be popular this year.
