San Francisco is set to turn into Gotham City, as city officials help fulfill a 5-year-old leukemia patient's wish to be "Batkid." The Greater Bay Area Make-A-Wish Foundation says the boy, Miles Scott, of Tulelake (too-lee-LAYK'), Calif., will be called into service on Friday morning by San Francisco Police Chief Greg Suhr. Miles will rescue a woman from cable car tracks in Nob Hill and capture the Riddler in the act of robbing a downtown bank. A flash mob will then summon him for another caper: a kidnapping involving the Penguin. He will receive the key to the city from the mayor around 2 p.m.
