With respect to my earlier mail, and bearing in mind the North South, East West layout of many North American cities, it stuck me that some North American readers might wonder how anyone could become uncertain of position (navigators never say lost) in a strange city.  Go to Google Maps and look at the centres of Hull East Yorkshire and Newark-on-Trent.  These are two places where I’ve been surprised to find I wasn’t quite pointing in the direction I thought I was.   Both are so old that they seem to have been laid out before the right-angle was invented, and believe it or not, both were visited by the Vikings around the ninth century AD.  DaveP
