MICHIGAN CITY, Ind. (AP) _ Doctors say a 6-year-old boy rescued from an Indiana sand dune is moving about the Chicago hospital where he's recovering.
 
  Dr. Diana Mitchell of Comer Children's Hospital in Chicago says Nathan Woessner can leave his room to visit the hospital playroom. She says he continues to improve and returned to a regular diet Monday. He's listed in good condition.
 
  The Sterling, Ill., boy was buried for more than three hours in the dune called Mount Baldy at Indiana Dunes National Lakeshore near Michigan City, about 40 miles southeast of Michigan City.
 
  Doctors have said Nathan is expected to make a full neurological recovery but may suffer lingering lung problems from inhaling sand.
 
  His grandfather, Don Reul of Galva, Ill., tells The LaPorte County Herald-Argus that Nathan's “not far from'' leaving the hospital.
