From my experience with scouting when i was "a kid"......
the thing that kept me coming to meetings, wasnt the uniform, the eagle rank(even though I did attain it), it was the things we did as a troop, We had a really good set of Adult leaders who kept us doing challenging things on our weekend outings, those alone kept kids coming back week after week.
I think boys can put up with some of the trivial issues like the cooking merit badges, and leatherwork class, if they know they are going to do some "fun/cool" stuff.
We went on a wild cave trip my 1st year in scouting, did lots of rapelling inside the cave, got very very dirty, and then i was hooked.
So I guess what I am trying to say is that the reason for the decline in scouting might not be scouting itself but the program being provided at certain troops might not be appealing, you can still fit in the BSA curriculum and challenge your kids along the way. There are not many groups set up where you can hike 15 miles into the back country of the App. Train one weekend, whitewater raft the next.
We had an adult who owned a large amount of land, he had built in a large shooting area in an embankment, we had a "rifle & shotgun" weekend, where we literally had a "blast" but a lot of parents might have a hissy about their son being around fire arms these days, so i dont even know if that allowable these days..
