my DD8 really LOVES her Girl Scout time. For her, she has told me before that she really prefers that all girl environment and I know when she goes off to camp, no one expects her to sit still and be bored. The girls plan their days there with the help of the counselors.
Even in our scout meetings...our troop is mixed (our school is K-12) levels and ages so there are lots of opportunites to mingle with different ages and explore her own interests. Everyone gets a chance to plan a meeting, share their intrests, be heard...basically all the things I think our kids are looking for.
I think it sounds like he would benefit from some kind of mentor to help him find "that thing"...have you considered sending him to a talent search? Or camp for gifted kids? It's hard to find someone like yourself even if you are non-gifted...maybe exposure to a higher concentration of kids more likely to be more like him
