<DIV><FONT size=2 face=Arial>Vidal, California also observes
America/Phoenix rules. I experienced this personally while camped
there in late 2009 - early 2010, but Vidal Junction is on America/Los
Angeles. My cell phone was indicating this and it also seems that the few
people in that ghost town of Vidal work in Parker, AZ.</FONT></DIV>

what it calls "Arizona Time" (Mountain Standard Time) year round.<BR><BR>Here
is what the site says about these changes:<BR><BR>
<BLOCKQUOTE class=cite cite="" type="cite">SD: The city of Fort Pierre
(legally in the Mountain time zone) and a large radius on the west side of
the Mountain/Central border observes Central time. Research determined that
the distance this observance extends to the west is a matter of disagreement
among the locals. After some effort to get a definitive answer I gave up and
arbitrarily selected 20 miles, though I heard credible opinions that it
stretched out as much as 50 miles. There are no services and very few
residents in the western part of Stanley county, so the point is somewhat
moot.<BR><BR>CA: Winterhaven California, in deference to its proximity to
Yuma AZ, observes Mountain Standard Time year round. This means that (like
AZ) Winterhaven does not observe Daylight Saving time. So this puts
Winterhaven ahead of California by one hour (in sync with Arizona) during
Standard time - in the Fall and Winter. And in sync with both CA and AZ
during Spring and Summer (Daylight Saving time). The dividing line of this
observed boundary is locally considered to be the "All American Canal".
