Query: The best starting point

I live near rivers and have seen others kayaking all the time and I wanted to know about this fun looking sport. This book lays it all out for you and tells you what you need to know. It starts with the gear you will need and how it works to how to paddle a boat. Armed with this knowledge I took my first class and I felt well prepared. I have now taken three classes and I keep referring back to the book to remind me of proper technics. I am considering buying a boat of my own and the book explains all the different types of boats and their uses for different types of water. I can see this book helping me for awhile as I grow in this great sport.
