  A sign advising the street closure is seen on Crenshaw Boulevard prior to the transfer of the space shuttle Endeavour in Inglewood, Calif., Thursday, Oct. 11, 2012. Beginning Friday, the shuttle heads off on its last mission, a 12-mile creep through city streets. It will move past an eclectic mix of strip malls, mom-and-pop shops, tidy lawns and faded apartment buildings. Its final destination: California Science Center in South Los Angeles where it will be put on display. (AP Photo/Jae C. Hong)
