The last time we saw a Luke in the desert this big, he was getting attacked by sand people, amirite, people?
Anyway, this is Luke Donald, World No. 1, "playing" a dune in Abu Dhabi's Liwa Desert. The desert is the world's largest uninterrupted sand mass, which means you're probably not going to get out of it in one stroke. No grounding your club!
Donald, of course, is playing the Abu Dhabi HSBC Golf Championship with Tiger Woods, Rory McIlroy and other reasonably well-known names. Alas, Donald is T32 after two rounds, sitting six strokes off the lead at -1. But at least he's got a little more experience getting out of the bunkers.
