A self-described eco-nerd Thor Hanson, scientist and writer, brought the nascent gorilla tourist program in Bwindi National Park, located within Africa's Impenetrable Forest, to life. With grace and good humor Hanson navigates the local customs, mores and bureaucracy governing everything from love to superstition to build infrastructure, hire and train staff, fend off millions of ants among many other creatures while studying and acclimating the mountain gorillas to humans in their midst.
