Laura Wilkins is walking to visit her mother in Grand Rapids, Michigan. She's in Tucson.
Wilkins, an artist, is streaming her walk 24/7, with a camera strapped to her head, connected to a solar-powered laptop in her backpack. "My artwork is about community and connections," she says on her Web site. "I believe that safety comes from trust, community and collaboration. I hope to use social networking, both online and traditional, to safely cross the country."
