Two special Top Gear episodes presented by Jeremy Clarkson, Richard Hammond and James May. In 'Botswana Special', our intrepid explorers, attempting to reach the Namibian border, have to traverse arduous salt pans, do battle with the Kalahari desert, and see if they can navigate the foaming torrents of the Okavango Delta. In 'Vietnam Special', equipped with, of all things, motorcycles, the adventurers have to cover the entire length of the country in just eight days.
