I think most boys think that it is the Uniform not the program that is not cool. My son who is an Eagle Scout and a sophomore in college used to look for reasons not to wear his uniform. However he rarely missed an opportunity to praise the
scout program to his friends. most of them thought that the things that he knew how to do, wilderness survival/no trace camping, winter tent camping, swimmong, canoeing and the like, were very exciting. Now that he is an "adult" Scout he has more Scout spirit than he ever had as a youth. So I think all boys in the program have Scout spirit to a greater or lesser degree, it just takes longer for some of them to realize it.
