A Rhode Island teenager who went missing in the forests of Wyoming is safely back in civilization.  Officials confirm that 18-year-old Nolan Reifsteck of Wakefield was located yesterday afternoon after being missing for more than a day.  Reifsteck went for a walk Tuesday morning in the Shoshone National Forest and did not return.  He was dehydrated and disoriented when rescuers located him yesterday, but he's not injured.
