I memorise major routes, cities, towns, river crossings and other strategic locations in mainland UK and have done since childhood (it was a sort of game) and I reference new locations according to their proximity/bearing to known places.... It's not perfect.... But it does mean that any notes I do take, will mean little to anyone else should security be a problem.
Failure to prepare mentally, is preparing to fail totally.
