A few years ago now I came across two female walkers at the end of the trail while heading to the top of Ben Chonzie for a Sunday afternoon walk. The hill top was covered in mist and visibility was a couple of hundred yards. They both had maps and compasses, they just didn't know how to use them despite one of them being a geography teacher, but at least they had the common sense not to go wandering off the trail in the mist. They knew their own navigational limitations. I am always surprised how many don't actually know how to use a map and compass even though they have the sense to bring them along.
