[EX Q]: I've heard it said that this is Kerouac's greatest novel. I still say that honor is held by On the Road, but this book is just as good. And it is his most spiritual novel. Kerouac combines his talent at writing with his philosophy of life and what you have is a powerful tool to enlightenment. This book should be read on at least two levels, as a work of great literature and as a theological tool. I can't recommend it enough.
[EX A]: Positive

[EX Q]: While old and out of print, this book is a very good way to learn the basics of photography. You have to ignore most of the references to digital cameras as the technology has changed a lot.
[EX A]: Positive

[EX Q]: First of all, the wire came out as i was untangling the cord, so it is very fragile. It is too tall. It's ears are too high above my girl's clit for her too feel anything. It's not the greatest thing in the world, and i do not recommend that you buy it. huge disappointment.
[EX A]:
Negative
