Mary Demetree's father, Bill Demetree, was involved in selling land to Walt Disney to create Walt Disney World. Bill and his brother, Jack Demetree, are featured in this post from the Orlando Sentinel:
"Intrigue. Master spies. Secret meetings. They seem like unlikely ingredients for the beginnings of "the happiest place on Earth," but the story of how Walt Disney World came to Florida has all of them.
Author Chad Emerson will talk this week at the University of Central Florida about the saga that brought Disney World to Florida — including the amazing acquisition, piece by piece, of a 43-square-mile parcel twice the size of Manhattan.
Emerson is a law professor at Faulkner University in Montgomery, Ala., where his areas of expertise include law concerning land planning, intellectual property and amusement parks. He's also the author of Project Future: The Inside Story Behind the Creation of Disney World, published this year."
