The iconic 1964 Chevrolet commercial "Pinnacle," set on Chimney Rock came from the keyboard of my late MSU advertising professor, Ken Jones.
I'm sure it must have rankled Ford to no end, who would want "their" mountaintop spot come hail or high water.
To the other point, I'm still wondering what OG liked so much about the Willys frame - considering that he was increasing the HP about 15X from standard.
