[EX Q]: You make it in rock and you think you can do it all. This book proves you can't. It is a truly poor excuse for a collection of haiku and it is particularly offensive because there are those who will buy it thinking it the real thing. Do yourself a favor and buy Higginson. You can look at this in a few minutes in the bookstore. It might be good for advanced classes in "don't let this happen to you!"
[EX A]: Negative

[EX Q]: With the type of closures and the amount of compression it is meant to give it's really difficult to put on. You need a hand to pull it closed in order to actually be able to close each of the 20 some odd hooks.
[EX A]: Negative

[EX Q]: This book has opend up my eyes. Robert Frost is in my mind one of the best potes in the world.
