Which isn't me saying "that's sufficient", but I did find it there at least: http://www.carrionfields.net/help/class/ranger.php

"Rangers generally become more comfortable with their skills as they spend more and more time within the wilderness, away from cities."

I'm not sure if we need a helpfile for wilderness time, but I can see how we might want one if it plays into a number of factors - at least something simple outlining the idea of terrain-times existing.

I'll wait to see what other folks think, then will proceed accordingly.

Thanks for bringing it up!
