[Q]: This set of assorted short tracks is hard to avoid if you want to create a track layout of even an intermidiate size. The male-male and female-female pieces will provide a dramatic increase in the number of layouts possible as you can now overcome the problem of curves returning to the starting position.This is a must-have for any Brio enthusiast.
[A]: Positive


[Q]: What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.
[A]: Positive


[Q]: I really liked this book,especially the fact [SLIGHT SPIOLER] That you get to see different people's perspectives at different periods of time. [END OF SPIOLER] I would reccomend this to anyone who likes books by Isaac Asimov or a story that takes place over a long time. ****
