Writer Levison Wood explores the largest sand desert in the world and travels through the Dhofar Mountains in Oman. Preparing to cross The Empty Quarter he climbs on a camel in such an ungainly manner that we now know what he's wearing under his dishdasha. One week into his arduous trek across this immense desert, he reveals he's fallen out with his guide over what he feels is cruelty toward camels. For his own safety he must stay friends with the locals on the next leg through the warzone of Yemen, where al-Qaeda, Isis and numerous criminal gangs operate. It gets very hairy.
