So I thought…I hope you have a good trip Steve. I didn't know so I googled it, apparently The antipodes of any place on the Earth is the point on the Earth's surface which is diametrically opposite to it. Two points that are antipodal to each other are connected by a straight line running through the centre of the Earth. Well well, you live and learn.
