The search for a missing Boy Scout troop from Lafayette has ended successfully.The six teens and two adult troop leaders  were stranded in Arkansas' Ouachita National Forest while backpacking and camping.  They were due to return to Louisiana on Sunday, but got stranded by heavy rain and high winds that hampered the search.  A rescue helicopter spotted the scouts campfire at 2:30 this morning and lowered radios and food to the troop.  The Scouts were reunited with their parents later this morning at a nearby staging area.
