The camp is three weeks away from home, at a college campus. It's run through Johns Hopkins, but there are numerous camps around the country through this program, so it's not like you're getting JH professors.
Having said that, it's a cool camp. Last year he did three weeks of Latin, and basically covered a Latin 1 high school class. They do academics all day, break for dinner and sports, and then go back to class for two hours. He craves this sort of intensity. They also do things like cookouts and dances.
It's nice for him to be in an environment where he is considered somewhat normal. We are all reasonably intelligent -- my dad was a NASA physicist -- but this kid is just unusually smart, and struggles in a regular school environment, socially and otherwise. He's seen as a bit of a weirdo, which makes me sad.
