Hitting the Trails with iPhone

Taking a hike is no longer a low-tech affair. Just ask David F. Gallagher (nytimes.com), who used Trails, a cool GPS application that not only helps you stay on the trail, but also offers “a nicely designed interface for recording and saving the paths of various hikes.” After saving them, you can export the data and share your hikes with others in Google Earth along with geotagged photos you took along the way.
