Since I decided not to go up to Portland for various dance events (sigh), I ended up staying in, reading Diana Wynne Jones The Merlin Conspiracy, putting possibly appropriate music on, and handing out candy to the five or so groups of trick or treaters who dropped by. It was cold--31°F, IIRC. They were a pretty reasonable group--mostly 10-year-olds or so. The last was was in a complete black robe with a black gauze mask--that one didn't say anything until I gave them some candy--then that one said thanks. Impressive.
