When I see 13yo Eagle, all I can think is that he can't even serve on staff at a council event.

I don't think he can go to our JLT camp - Makes me feel old.
I tend to think in terms of capital letters. I'm thinking of a boy that is working on his Eagle. In my mind, he may earn his eagle (small e) but will never be an Eagle (capital E) And that has nothing to do with his age, and everything to do with his leadership skills and attitude.
If he sticks around, he will have the chance to change my mind.
I want my son to be an Eagle with a capital letter if he makes it.
My son earned his Arrow of Light and could have bridged when he was 10yr, 6mo; but he waited 2 months to bridge with his den. If we had put him into a troop that was active in the 'First Class, First Year' program he could be pushed into earning his Star by the end of summer or sooner. But, I would have missed him realizing that he WANTS this. The look on his face now makes it worth waiting as a Mommy.
Disabled Scouts are a challenge, but so rewarding. I admire your stick-to-it-tiveness. I'm curious - did he do the typing or did you take dictation? I ask because I have a nephew with some problems in writing. He is very articulate, but don't ask him to leave his Mom a note that says you called. He is grown and thinks he has failed academically and I'd love to be able to share that there are others who function, and suceed. And, since I have taken dication for kids for years, I don't have a problem with it - it brings it's own challanges to the writer.
