In thousands of Earth orbits, the space shuttle Endeavour traveled 123 million miles. But the last few miles of its final journey are proving hard to get through. Endeavour's 12-mile crawl across Los Angeles to the California Science Museum hit repeated delays Saturday, leaving expectant crowds along city streets and at the destination slowly dwindling. Officials estimated the shuttle, originally expected to finish the trip early Saturday evening, would not arrive until later Sunday. (AP Photo/Alex Gallardo)
