Kayak Magazines/Newsletters/Periodicals/Websites
While I was on Vancouver Island summer 2005 I discovered Easykayaker.  This excellent book about easy saltwater kayak adventures from the Island led me to the second book Kayaking Vancouver Island and to a one day class by the authors.  Gary Backlund and Paul Grey have a great attitude about kayaking, stressing having fun and staying safe.  They focus on easy-to-use launch sites, easy-to-paddle trips, easy-to-find info, and easy reading narratives. Their trip descriptions give you and excellent idea of what to expect at each location.
Deep site with lots of information on canoeing and kayaking. From Buyers' Guides for canoes, kayaks and accessories to articles, classifieds, photos, outfitters, and dealers.  They have ongoing contests with great prizes.  Even if you don't win you learn about lots of new Kayak products.
