Query: This book was long overdue

While in my late twenties I traveled throughout the third world for nearly four years like a forerunner to the present day backpackers. Of the zillions of situations I encountered while staying in flea bag hotels, riding chicken buses, going deck passage on over crowded freighters, hitch hiking through central Africa, one memory stands out. I was crossing through Tanzanian immigration near Arusha. The Black Tanzanian immigration officer asked an older Austrian gentleman in front of me what his occupation was. The Austrian in broken English replied, "I'm an expert." To which the Tanzanian remarked, "Just what we need, another expert!"I can wait for the paperback to come out. I'm still a penny pincher.
