Here's a sample from his 2005 essay for Esquire that the book is sort of based-on:
The dinosaurs are the first things you see when you enter the Creation Museum, which is very much a work in progress and the dream child of an Australian named Ken Ham. Ham is the founder of Answers in Genesis, an organization of which the museum one day will be the headquarters. The people here today are on a special tour. They have paid $149 to become "charter members" of the museum.
"Dinosaurs," Ham laughs as he poses for pictures with his visitors, "always get the kids interested."
AIG is dedicated to the proposition that the biblical story of the creation of the world is inerrant in every word. Which means, in this interpretation and among other things, that dinosaurs coexisted with man (hence the saddles), that there were dinosaurs in Eden, and that Noah, who certainly had enough on his hands, had to load two brachiosaurs onto the Ark along with his wife, his sons, and their wives, to say nothing of green ally-gators and long-necked geese and humpty-backed camels and all the rest.
(Faced with the obvious question of how to keep a three-hundred-by-thirty-by-fifty-cubit ark from sinking under the weight of dinosaur couples, Ham's literature argues that the dinosaurs on the Ark were young ones, and thus did not weigh as much as they might have.)
