Could you get a tour of your main branch public library? Could detox just look like a big bag of books from the library, time to play, tinker with broken stuff (supervised...use you tube for help), how about cleaning out his room? What about exploring new things like a yoga for kids DVD and nature trails and centers in the spring....for now he could research places to go in the spring...in my area we have botanical gardens, nature parks with programming, state parks, pioneer villages, forts, other historical sites, lots of theater, museums, etc. just select some and see if they have free days or discount days or special deals.

My one son is all about research.
