Some amazing costumes! Perhaps my favorite was a robot made of cardboard, painted green. My favorite line, when a group of pre-teens were standing in the doorway picking their treats: "Wow, I love books! It's like a library in here." I built a story-and-a-half bookcase in my living room, which you can kinda see in this photo:
Hooray: Kids love books!
