Cameras Looking for Wildlife on the Trail

Sterling Meyers writes in the 10 February 2008 Washington Times under the headline "Cameras to aid in trail preservation" about the effort to document wildlife along the Appalachian Trail with 50 digital cameras on loan from the National Park Service. The cameras are equipped with infrared heat sensors that trip the shutter when a warm body passes by. A target of special interest is the elusive and possibly extinct eastern cougar.
