I look at the North Star for True North, ha. Aren't we off by 8 degrees from Magnetic North? What year was it when all the tectonic plates of the earth moved and changes our direction a bit? am I saying that right?
Not so much the change due to continental drift over a relatively short period of time, but variations in the earths magnetic field causing the magnetic poles to wander affecting the magnetic declination.
We'll all be buggered when the poles flip!
