Driving at morning

Looking through the windshield, everything is lightening
Ash colored two lane in tow, highway lines are heightening
But i've been driving all night, wondering what to do
cause i've got miles of county lines before i'm through
the fog on the offramps is thin, exit signs are turning green
Empty cup off coffee in the floorboard, i can feel it in my bloodstream
a transfer truck is moving lanes way up ahead
red tail-lights blink i start to think i'm going to find a bed.
the sun comes and goes through the trees like notes making a minor chord
Defrost almost animates the dust across the dashboard
the sun reflected light projected all i see
is flashing like a filmstrip right in front of me.
