I don't know too much about Boy or Girl Scout. My two daughters are both in-door girls. But they have done some other type leadership related ECs such as debate team, Model UN, Junior Statesmen (JSA). There are so many activities that young people can engage these days. The trick becomes how to choose the best ones for your kids.

I really believe that the best ones should be the activities that they truely love and can do well on. What the college admin officers think is more secondary. If a kid has a shot at Harvard but does not get in, it is not the end of the world. I am sure that he will have a great future in other universities that provide equally great education.

Boy scout sounds like a great activity. If your kids enjoy it, then go for it. Otherwise, you can also choose something else.
