Hi Tiffany,
The NE has an abundance of camps. Check out
www.TheEducationalRegister.com, a free guide to private schools & camps. Specifically for gifted, I suggest your son participate in one of the talent searches. Duke Talent Identification Program (TIP) or Johns Hopkins Center for Talented Youth (CTY) cover that region (and offer summer institute at a variety of college campuses across the country, not just Durham or Baltimore), and encourage them to test using the EXPLORE or PLUS tests (5th & 6th grades) and then SAT/ACT (7th & up). My kids seem to really like taking these advanced level tests. Students with qualifying scores are invited to a choice of programs. We have only done the Rocky Mountain Talent Search program, but may consider TIP or CTY for subsequent summers. The talent searches also provide booklets with a million awesome camps all over the country which list ages and topics of interest to help you select. Many require that the student is 12 years old, but not all.
If you don't want to go this route, check out hoagiesgifted.com and they have a lot of information or check into the many esteemed universities (Harvard/Yale, etc.) because most of them offer some kind of pre-college program for gifted students.
