(Salem, OR)  --  Campfires and open flames are banned at Oregon state parks in response to the Substation Fire.  That's the word from Governor Kate Brown, and comes after she declared a state of emergency.  The ban applies to wood, charcoal and other flame sources that cannot be turned off with a valve.  Liquid-fuel stoves and other valved devices are OK, but cannot be left unattended.  Officials hope the ban will reduce further demands on limited resources.
