GoodGrief.....Good Grief! How sweet it must be! The absence of such "structure" must simplify life quite a bit!
In the early 70's....flying Jet Rangers around Upper Volta, Ghana, Mali, and Ivory Coast was like that pretty much....as lots of the areas on what maps we did have were blank and were labelled "Reported Mountains, Valleys, and Streams". We hand drew some of our own maps for areas where there were none to be had.
There we were back to Mag Compass....Clock....and the ability to imitate a Homing Pigeon. Add in not being able to speak French or any of the local dialects made Life all the more enjoyable.
