(Hood River, OR)  --  Officials say a 75-year-old hiker who got lost in the Mount Hood National Forest last week is now safe.  David Bullock and his wife were hiking together on a trail from Laurence Lake, but got separated around noon Thursday.  Bullock, along with the couple's three dogs, were found in good condition yesterday afternoon.  Bullock, who's an experienced hiker, says he survived on stream water and stayed warm by staying in a shelter he built.
