9 years ago in Feb was in Veges. Took a road trip to the Grand cayon. At the Hoover dam the bus was inspected by (Border?)Guards. It was also announced that they was an hour time diffrence between Nevada and Arizona.(Except on Indian lands) Did not see the GC as visabilty was about 50 yards and snowing
Arizona and Hawaii still abstain from DST. There used to be more states that did not change their clocks, but over time [pun intended] they relented. If there were guards at the Hoover Dam, I would imagine that they were there for security, checking for explosives...but I have no first-hand knowledge.
Then you will have to come back. The GC is amazing anyway you can see it. And it changes with every time of day.
@Joe Riley , that was beautiful. They matched the music to the video perfectly. Especially at the end when the crescendo matched the lightening.
