Well, I've seen it. My 1st PL had Eagled at age 13. Great guy. Stayed in the troop until 18. His younger brother was a good scout as well.
There is something to be said for moving your leadership development along. Then use what you've learned by getting Eagle to make your high school career better.
But that's just me.
How do you all help your young eagles (if you have them) get the most out of their early achievement?
