In case this is broken too, know that the MSAR units directory
(http://www.ibiblio.org/msar/units) under California has a links
to this document. It is on the California Governor's Office of
Emergency Services' website. The document title is unclear (it
varies from page to page), but the cover page says "Law Enforcement
Mutual Aid Plan (SAR) Annex: Mutual Aid Guidelines: Search
and Rescue Mounted Teams".
