Dark mornings

I've had my lights on my bike on the way to work for a little while now, but this morning was the first that I felt it was truly necessary. Camera actually captured too much light so I had to dim the brightness to what it was like.
I depart at about 07:15 to arrive by 07:25 - a nice short commute. The return journey takes twice as long as it's all up hill (over 120m of vertical ascent!)
