However, I can't let well enough alone, so here's an idea that I've been thinking about since I heard it. I'm pretty sure it was +Jerry Durante who first suggested this, but here's a thought that makes an awful lot of sense to me:
Any adventurer should be able to do anything that a Boy Scout can.
That makes sense. All adventurers are expected to tromp across various wildernesses and spend ridiculous amounts of time with limited supplies in cramped and dangerous underground crazy places. One might begin to expect a certain degree of competence at general sorts of useful things just to survive such experiences. You just might. I know I do.
So, I started to think about exactly what it is that Boy Scouts get trained to do. I myself never got past Webelos (which is kind of a shame; I dig all the stuff the Boy Scouts do, just not some of the core tenets or failures in leadership that the organization has experienced), and it's on its way to three decades since those days for me, so it's time to hit the books for some research.
And for our research, I decided that it's best to go for the original. Yes, just as we old-schoolers love to consult 1e or OD&D (or some iteration of Basic) as the ursprung of all knowledge, I've decided that it's best to head back to 1911 for the Boy Scout Handbook's own 1e. Really, the reason I went back this far is I wasn't really sure where I should stop. Is there a definitive edition? Is there a preferred one? Rather than start a completely different set of edition wars, I figure it's safe to just crack the pages of the first edition.
According to the 1e Handbook, there are three ranks of Boy Scout: Life Scout, Star Scout and Eagle Scout. Attaining a new rank is a function of earning enough qualifying Merit Badges, which are a sort of certification (expressed in the form of a patch given to the person who earns it that is worn on his uniform) expressing a degree of competence or proficiency in a particular field. I'm not sure if this overall Life/Star/Eagle Scout structure is still in effect (I presume there are still Eagle Scouts, what with that idea still being firmly within the public consciousness).
To attain the rank of Life Scout, a scout is expected to earn the following five Merit Badges: first aid, athletics, life-saving, personal health and public health. The Star Scout rank is gained by accomplishing an additional five Merit Badges, and the reason that we as lay people recognize the Eagle Scout as a thing is that the Eagle Scout earns at least 21 Merit Badges in order to be called that. Some of the skills that you can earn Merit Badges for -- even in 1911 -- aren't exactly applicable to your typical D&D setting, but let's take a look at the rest of the badges and what sort of proficiency they imply. (I'll list all the badges, but put the ones that I don't think would apply in most settings in [brackets].)
