Several citizens will be demanding an investigation. This particular area where the Arrowhead Springs Resort is/was located was up for development. There is a natural hotspring there which has been closed to the public for years. Fires and development appear to go hand in hand in San Bernardino County.
When the package concerning this fire is sent to the appropriate individuals in power, I will let you know so that you can also write letters and/or call these people.
