Arlanda in the Dark

I've always liked the drama of outdoor working places at night. The contrast of darkness and bright spotlights. 
We've just got off this plane after flying the first leg of our journey; Heathrow to Arlanda (Stockholm). Now we are in the midst of the 4 hour wait for the final leg; Arlanda to Sundsvall/Härnösand.
It's a real winter temperature here (-10C) but there doesn't seem to be any snow. Yesterday Härnösand had the deepest snow in Sweden, just over a meter deep.  So I guess we'll have a little digging to do, getting to the front door, when we get  home just before midnight tonight.  Tomorrow they'll be more digging...
