Although NCF's map reading skills are oft commented upon, there are times, when following a route, the proper course is to read the map "upside down." Perhaps, s/he forgets that when asked for directions/locations etc, the connection between paper and reality evaporates? A sign of getting old, perhaps - like many of us?
I find that the puzzles are much easier/quicker to solve because of the data we can access so easily on-line. In that sense, I think that they are not as challenging as they used to be rather than describe them as less enjoyable. The solving of the incidental clues often turns up some interesting facts.
