Ghost passing

Wasn't sure what to name it - as I was never good at naming photo's.... But this was a bridge near the end of the Redwood Forrest, and close to the Oregon border. (that one will probably be posted before I get home as well)

Anyways, I was trying to get one down the tunnel, but it required a 15 second exposure and cars kept coming from either direction, so I ran to the side with my tripod and clicked with the car coming hoping that I got something from all the time trying to get one from the middle of the road. ^^
