Fire on the east side of route 21 around mile marker 20. When we drove by around 2:55pm it was only a few square yards, obviously has increased in size. Three vehicles were parked at a pull-off nearby. A man appeared to be on a radio - moments later a sheriff came to the scene. About five minutes after that, the Robie Creek Volunteer Fire Department rolled out to assist. As far as I know, no structures are threatened at this point.
