When is solar noon?
At the equator, 0 degrees latitude, the sun angle at noon at the equinox is 90 — 0 = 90 degrees, or directly overhead.
And the closer you live to the Equator the more even your day/night is.
I used to live on Guam which is 13 North and the sun rose and set at 6:30 and 1830 everyday throughout the year so it was dark at 1900.
In a perfect world I would have a trailer pads just south of the Mackinac bridge. And somewhere in the keys.
