Hi Mr P., .....Well, 'back in the day'......did'na have no 'fancy gismos' - they were'nt invented yet - just a map, (WAC) ruler, and a sharp pencil.
Learned how to nav at rather 'low levels' and assess drift by observation. Never got 'lost', and keeps yer head outside the window...fer traffic and dem low flyin' eagles etc....
Sometimes, semi trailers yousta flash their headlights at me over the Nullabor, and I would give'em a wave. Dem highway 'milestones' of the day were great fer G/S checks.
'appy 24...........
