In 1819, the renowned Scottish ornithologist William MacGillivray walked from Aberdeen, Scotland to London, England in order to visit the natural history collection at the British Museum. If the modern M6 had been available to him, this would be a distance of 548 miles – one way. However because Mr. MacGillivray took a more scenic route that included Ben Nevis, the distance he walked totaled 837 miles; a distance he covered in approximately eight weeks.
