Thanks to Greg Ford for his technical expertise. Thanks to Mari Omland for bringing me to Africa years ago. Many thanks to Laurent Chaline for helping me with my French translations and to my nephew Benjamin Mackenzie, whose recent semester in Ghana supplied me with many details. Thanks to Dr. Ben Osborne for his medical advice, and to Peter Haas for explaining global oil economics to me, and finally to my wife Jen for helping me along the way.
