This was a fantastic book, full of colorful stories, and lots of facts. I was already aware of Arrow Development, but had no idea that they were responsible for the invention of so many different types of ride systems. The book details, their entry into the business. Their eventual association with Disney and how it all started with the hand-built Mr. Toad cars, and continued from there. Water rides, such as It's a Small World and Pirates of the Caribbean, in addition to log rides. These were the guys who invented the corkscrew roller-coaster. They built rides for many other parks also, and it details those projects also. I was fascinated with everything that I read in this book, that I couldn't put it down until I had finished reading it. A must-have book for any theme park / roller coaster enthusiast. 5 stars, as fas as I'm concerned!!
