This area is mildly confusing, even to the locals I was with. The easiest way to get to Rocky Knob is to follow the Rocky Knob Trail map. We saw red blazes, white blazes (Appalachian Trail), but no orange blazes where the "getting there" directions mentioned. By following the map I've mentioned, it's a whole lot easier to get to Rocky Knob.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
