That is the problem with Boy Scouts (even Cub Scouts). The den disbanded, and they needed another den leader. Besides my son I have twin girls. I'm already a Brownie leader. I can't be active in both girl and boy scouts, so we stopped doing Cub Scouts.
When the girls are old enough to stay at home by themselves, then it might be easier to do Boy Scouts.
That's the problem with any non-sport youth organization. It needs the adults to help run it. Not that the sports teams don't need adults, but they need fewer.
How's the GSUSA unit going?
