A decrease in emphasis in camping? Not at all. In fact, camping and the leave no trace program is stronger than ever, making today's Boy Scouts the best campers of all time. Unfortunately, state parks and national parks are in bad shape, and it's getting tougher and tougher to find places that aren't overwhelmed with RVs, etc.
Also, the Scouts of today do a lot more than camping...as they should. Boy Scouts is all about preparing our young men...and women...to be the leaders of tomorrow. Camping, sure, is a part of it. But camping was a way to attract youth to the LEADERSHIP program. BSA, fortunately, is adapting to the changes in our youth and appealing to them in a much broader way.
It's up to the troop. One of our troops does almost no camping. Another troop does a ton of it.
