I was in Scouts (both Cub and Boy). I think I made it to Star (two levels below Eagle) before I discovered an Explorer Scout post that focused on astronomy, and switched to that.
Spawn (my son) was in Cub and is now in Boy.
His pre-move (in California) Cub Scout pack met in the school he went to.
His post-move (in Illinois) Cub pack and Scout troop both meet in a church.
I think it's important to be knowledgeable about the culture you are being raised in. Here in Suburbia, church is a sizable part of culture. I want him to know who Adam and Eve and Noah and Jesus were, and why other people revere them, even if he ends up not revering them himself.
After investigating the Mormon influence in Scouts, I've come to the conclusion that it's only really noticeable way high up in the organization, at Council level and above. Nothing trickles down to pack, den, or troop leaders, and so it never gets to the boys.
