Yellow Road

This photo was obviously edited in Photoshop! First, there were two road signs in the foreground that were too distracting. Then, I used five different Curves, Levels, and Hue/Saturation layers to obtain enough contrast in the trees without making them too dark.
The yellow lines were the easiest. Since they were the only yellow element, I duplicated the photo and used Select/Color Range to select them, erase the rest of the color photo, boost the saturation a little, and superimpose them on the B&W version.
Please let me know what you think.
