(Vancouver, WA)  --  A man and child are recovering after being rescued from the Columbia River in Vancouver.  The Multnomah County Sheriff's Office says the young boy fell into the river near Marine Park yesterday, prompting the man to jump in after him.  Police say the current carried the two away from the dock and pulled them downstream.  A Marine Patrol unit pulled them from the water.  Police say the two were chilly but otherwise uninjured.
