[EX Q]: Review: I purchased the movie and wanted to read the book also. It is sad as well, as I see life lessons in reading this book. It follows the film exactly, especially the beginning, in my opionion.

[EX Q]: Review: There are plenty of tension rods out there. The _only_ advantage of the Umbra rods is that they look better. (Why other manufacturers haven't figured out the design part is anybody's guess.) The problem with the Umbra rods -- all of them -- is NO tension. I have tried these repeatedly.... Why? Because my local hardware store carries them, and they are readily available elsewhere, and I have opted for form over function. Every single Umbra rod I have used fails drastically. They simply cannot bear any weight. Or, to put it differently, they cannot exert enough force against the surfaces they extend out to for them to bear any load. Worse, the springs that are the key element in sustaining the tension tend to fail. When those springs fail, anything you have suspended by the rod will come down. If it's a lightweight drapery panel, you may be in luck. Otherwise, forget about it. 
 Polarity: Negative
[EX A]: True

[EX Q]: Review: The book WAS good in its time but EVERYTHING related to traveling in this area of SE Asia, especially Laos, has changed drastically in the past three years. Frankly, a 1996 edition should be sold as remainders at about $2, then someone who wanted only info about the people or the temples could get ethnographic info only! I was in Laos this past August 1998 and most published info, except the Internet updates by an Australian in Nong Khai,Thailand, who does visas to Laos, was wrong and very outdated--especially the most important things like availability of visas and safety of bus/road travel. Real traveling info from books like this that are so old could be very misleading!
