The United States is maybe the best country in the world for sunsets, owing to the fact that it has the south and southwest, the Rockies to influence magic hour, and the Midwest has the great plains and storms.
The desert of the southwest is ideal for medium and upper-level clouds during monsoon.
The south, mainly the west coast of Florida, has land-affected heating which contributes to sunsets on the Gulf of Mexico.
In the northwest, you can get above the fog and clouds in many high spots during winter, but this can be very hit-or-miss- a number of factors can complicate efforts in succeeding at this. This includes too many high clouds, rain, and the conditions rain brings.
