Having dealt with hyenas, bandits and a small thing called a war in Chad, you would expect explorer Michael Asher to be able to navigate his way round the streets on a weekday morning. But an hour and a half after he left his Causeway Bay hotel, armed with a map to guide him to his appointment at The Landmark, Asher was nowhere to be found. He hadn't rung the hostel, but that wasn't surprising. What would the man, who with his wife were the first foreigners to cross the Sahara, say? 'I'm lost'? And this was after Asher had spent a couple of nights at the Furama, not a day's camel ride from The Landmark, while visiting to speak to the Royal Geographical Society about his desert exploits. Of course, the Sahara is a bit different from Hong Kong. For a start, there are few landmarks in that expanse of sand. Compasses and the sun become important. Could it be that the intrepid explorer off to the New Territories trying to find a break in the clouds and a spot of sand?
