Well, no, I don't. I'm not trying to be sarcastic, but if you take away magic or other supernatural abilities what are you left with?
The ranger class has always been pretty nebulous to me. LOTR was a low magic world, Aragorn in D&D terms had little more than expertise in medicine. If you look at a more nebulous wilderness warrior ranger, that is likely a dex based build that uses some kind of bow and is good at survival and stealth. It's easily attained a number of ways.
So don't go around telling people what they know, because I don't know what you think I know. You know?
