Janice Baker reports that Las Vegas will soon have its own Grand Canyon. Developers are creating a fiberglass and cement canyon two stories deep and one hundred ten feet long for a mall scheduled to open this summer. They expect to get at least 12 million visitors...double the number of people who visit the real Grand Canyon each year. Las Vegas' fake canyon is latest in what tourism officials in Arizona see as their neighbor's exploitation of the canyon. In the second part of this story, Mike Lamb reports that Las Vegas already markets Arizona's natural wonder by hosting charter planes and buses for day-trips to the canyon. That means fewer tourism dollars are going to Arizona...and less money is going to preserving the site.
