Which do you prefer?
For me, it's sunset. There are 2 main reasons for this:
1. It's prettier.
2. I don't have to get out of bed disgustingly early to see it.
Don't get me wrong, sunrises are pretty awesome too; they carry the promise of a fresh start, and the birdsong at sunrise is amazing. But, for now, I will maintain my preference for sunsets.
Take a look at these pics at the LiveScience - sunsets, sunrises, eclipses, and solar flares are all included. And some of the sunrises are pretty spectacular. But not enough to warrant me freezing my butt off to see them.
