Sunset can be the sexiest time of all day. All colors may happen to be there, from orange, purple, red, yellow, blue, and so many more, in a setting of mother nature's unbelievable snap, just like a picture, but in massive scale. I've experienced some sunsets from different spots in my town, and am still amazed with what nature has provided me so far.
