Border Field State Park, the southwestern-most point in the continental United States, has a lovely view of the Pacific Ocean -- and of the fence that separates Southern California from Mexico. Now, the U.S. Immigration and Naturalization Service is fortifying that boundary through the Triple Border Fence project, which entails building additional fences and a high-speed patrol road, despite the area's sensitive ecology. Critics include two federal agencies as well as state, county, and local governments, the area's two congressional representatives, and numerous environmental, human rights, and archeological organizations. So why is the project still going forward? Deborah Knight reports from the border, only on the Grist Magazine website.
