Interesting article in September issue of National Geographic magazine about the threat of commercial development to the Grand Canyon. The author and his friend are attempting to hike the 650 miles of the canyon. He says that no trails exist on 95% of the north rim and 80% on the south rim. He also says that fewer people have hiked full length of the canyon in a single trip (10) than have walked on the moon (12),<br>
