    Learn the story behind the creation of Walt Disney World. In 1964, when Walt Disney and his brother Roy decided to build a second theme park in the Florida swamplands, they kept it super hush-hush. Why? Well, if word got out that they planned to buy up lots of land, the price would have skyrocketed. So the Disneys cleverly covered up their trail, avoiding the Orlando airport and even using made-up names, like Walt and Roy Davis, for their flights. The deception worked. In covering the history of the Most Magical Place On Earth, Joan Holub takes readers both behind the scenes and underneath the park (there are secret employee-only tunnels that form one big circle under the Magic Kingdom). Loaded with fun facts, this book is a great companion to Who Was Walt Disney?

Manzanero explains why Area 51 was established and reveals the mystery behind those unidentified flying objects in the sky. Check out this book and decide what you believe.
