Washington, DC – The National Park Service is stepping up the use of technology. The aim is to help capture the interest of a new generation, and grow support for places like Yellowstone. At the Benefield Elementary school outside Atlanta, children take an online, Yellowstone field trip. The school's technology coordinator says kids are interested in the country's first national park, but some can't afford to actually see it. E-trips offer a mix of animation, video, and scientific facts. Nationally, parks and historic sites are using technology to become more accessible to a younger and more diverse audience. The Park Service says that for parks to endure through the generations, people must know them and feel an emotional connection -- even if they never get closer than a webcam.
