I have thought hard about what was romantic about sunsets, or being up high.
I have walked up a mountain but it was very hard slog getting up there, and you dont really want to come down a mountain after sunset as you could fall over in the dark.
Also, since I live out west coming home from work with the sun going down I have to wear sunglasses, and going to work, with the sun coming up you get sunstrike heading the opposite direction.
I think looking at sunrises are better for me though especially on eastern beaches. Western beaches can be rough and wild, and driving in the dark after sunset is not romantic for me, or being in the car with someone after dark especially if they dont know where they are going or maybe had a drink or so. Its dangerous where I live.
