What is the furthest north, south, east and west you've ever been? (By Longitude please.)

I did not say that.

You may be thinking of this quote:

That was in response to the question “What is the line we can’t cross over and still call it furthest East or West?” I meant that there is no point at which heading “east” suddenly turns into heading “west”. Obviously there are two opposite longitudes on the planet at which negative longitudes becomes positive, and vice versa.

My argument with you was about this:

Because there’s a definite difference in ‘eastness’ and ‘westness’ of your longitude. If you ignore that difference, you might as well not bother

That’s not an argument against the Prime Meridian being the reference point for longitudinal coordinates. There is no argument against it, because that’s what it is, by definition.

But this is turning into something of a hijack so I’m done with it.
