For many people, a 5 a.m. wake-up call isn't too far from ordinary. Maybe they wake at 6 or 7, so while early, 5 a.m. isn't a huge stretch.
As someone who works as many nights as I work days, I'm more likely to bed at 5 a.m., than to wake at said hour.
So to be awake, alert and driving by 6 can be a painful experience, especially when the morning was foggy and the streets unlit. By 7 a.m., however, the sun had risen and the view looked like this.
I don't anticipate waking at 5 every morning, but that day it was worth it.
