Normally, picking up hitchhikers is a really bad idea. You never know what sort of ax-wielding entrepreneur you're going to get. But if you happen to see this friendly LED face on the side of the road, consider giving it a lift. That face belongs to hitchBOT, of Port Credit, Ontario, Canada. On Friday, it left the Peabody Essex Museum (PEM) in Salem, Massachusetts for an adventure on America's highways. Its final destination: San Francisco's Exploratorium. On the way, hitchBOT hopes to see some sights including Time Square in New York City; Millennium Park in Illinois; Mount Rushmore in South Dakota and the Grand Canyon in Arizona. If only there were hotels it could stay at or shows it could see along the way. There's no timetable for when it will finally reach the City by the Bay, but you can be sure that it will have plenty of tales to tell once it does.
