"From finding food, water and shelter to traveling for commerce, trade and eventually exploring the world, humans have always had to find their way from one place to another. Are We There Yet? examines the evolution of how we navigate the world.

Then came the invention of maps, faster transportation and eventually technology, like satellites and GPS. And from the depths of the ocean to faraway planets, there's still plenty of exploring to do. Where will we go next?"-- Provided by publisher.
