18/365: Stop the Car

Driving home tonight, thinking of my shot options for the evening, taking the backroads...

Stopped in the country, and shot the sky for a bit. Turned around and shot my car too. Lighting info after the jump:

Strobist info: this is a 126 second exposure, which is how you get the stars to register at f/4, ISO 200. I walked behind my car with a single Canon 580exII and popped the flash a buncha times toward the ground and up toward the car. Then I walked around and popped the driver side of the car a few times from camera left and right. Colored tweeked in PS. Anyone care to guess what the dotted line is?
