Imagine a utopian society with music streaming from lampposts and golf carts providing all transportation. Well, "The happiest place on Earth" might not be Disneyland, it might just be gated retirement communities. Developers are buying and gating massive plots of land in warm climates and installing aesthetically pleasing downtown centers designed by Universal. But these developments don't allow for children, and indeed segregate themselves from much of the outside world. In his new book "Leisureville: Adventures in America's Retirement Utopias," author Andrew Blechman explores beyond the facade of these surreal communities. Larry speaks with Blechman about what stirred his interest in the subject as well as the benefits and drawbacks of living in paradise, removed from society.
