We have the technology to eliminate most of what paid professionals at councils do now.
And, I have been thinking about this a lot lately... what SHOULD council do for units, other than provide program opportunities that units cannot get (easily) on their own? Shooting sports (SORRY!! Range and Target Activities), higher level aquatics (sailing , kayaking, canoeing, rowing, lifesaving), and climbing....
You do not need swimming pools. (Although they are helpful.) But you do need a safe swimming hole
You do not need dining halls. (I would submit these are actually detrimental to the skills needed for outdoorsmanship and campcraft .) Scouts should be cooking for themselves.
You do not need hot showers. (Although they are nice.) Scouts should learn field hygiene and sanitation.
You do not need flush toilets. (Although they are nice, too.) See above. I would admit that, due to the number of people you'd like to access your camp, that pit toilets would be a most helpful concession. And local laws may be prohibitive in many places...
Heck, you do not even need running water. (But you do need a potable water source, which could include bringing your own.)
You need a patch of decent ground or woods. Imagine how easy and cost effective this would be if we did not have all that infrastructure. A local council should have a good sized camp to provide access to the outdoors.
It really isn't that difficult to live under canvas for a week.
When BP said "A week of camp life is worth six months of theoretical teaching in the meeting room" he was not talking about the monster of summer camp merit badge mills we have created across the country.
