Before moving to Nevada for the DA, I lived in Manhasset, and my son spent a summer at the Hofstra gifted camp. I think he was 8 or 9 at the time. It was fine, and he had fun, but it wasn't terribly challenging. He had better luck at the CW Post's Center for Gifted Youth summer program, which he wound up attending for quite a few years. He found he connected more with his peers and the instructors there.
