Amidst the giant sand dunes in Huacachina Peru, I find myself cajoling the Peruvian president to take a dune buggy ride. But he has a bum leg and wants to sit this one out. Only problem: he's the star of this show. No president. No show. So it's my job to hopefully get him up on his feet and then seated down in the dune buggy. They didn't teach us any of this stuff in film school.
