Thanks to Ms. Cartwright's class at M C Williams Elementary in Wilmington, NC, for sending me the photo above. Earlier in the spring I'd sent them a Percy poster as part of a contest. Before their end-of-grade testing, they held a "Camp Half Blood Day" to train for the tests. They held a pentathlon with arts and crafts, made their own T-shirts, and selected the cabins that they thought they belonged in. Cool idea!
