I mounted a 7D to my dash and shot my whole trip from Atlanta to L.A.  I have to admit that I think I got better at controlling the exposure, frame rate, and general process about the second day into the four day trip.  Definitely check out the thunderstorms I drove through in New Mexico towards the end of the video.  Very cool stuff!
