Query: Always an eye opener, with great photography

National Geographic is simply a great magazine for people interested in the world. The world of peoples, the world of animals, the world of plants, the world of beautiful places, the world of ugly places. While the text can sound aloof at times, the photos are simply world-class. In fact, I read NG mainly for the photographs. As the Chinese proverb goes, "A picture is worth a thousand words." NG hires some of the best portrait and nature photographers who trek thousands of miles each year to bring NG readers amazing and sometimes mesmerizing photos. This magazine truly opens one's eyes and mind.My only minor complaint is the large number of ads in the magazine which sometimes look almost like part of a real story.BTW, Amazon is charging too much for this magazine. You can subscribe on NG's website for almost half of what Amazon charges.
