Bangor native James Kaiser, who wrote “Acadia: The Complete Guide,” stands with his camera atop Beech Mountain recently while photographing scenes for his guidebook. The fourth edition of the guidebook will hit bookstores March 29 and will display the Acadia Centennial logo, signifying Kaiser is an Acadia Centennial Partner and will be donating 5 percent of his book sales to Friends of Acadia, a nonprofit group that works to improve the park.
