...always depends on your means of travel. Just ask the engineers who had to transport the KATRIN Main Spectrometer from Deggendorf to Karlsruhe. The map halfway down the page says it all. Because there was no way to move the spectrometer directly across the 400 kilometers between the two places, they had to move it along the shortest path across which they could actually transport it: a route that was, more or less, 9000 kilometers long.
