I've seen a few other parents of scouts, and scout questions, on this forum so I thought I'd open a thread specifically for scouting.
As far as I know, Cub Scouts progress through their levels by grade level, once they cross over and become Boy Scouts then age is no longer a reason to hold a boy back.
For the parents of some of the grade accelerated kids, did you keep your Cub with his age peers? Did they cross over to Boy Scouts at the typical 10-11 age?
