I would actually suggest going from north to south because of the prevailing winds and I believe the terrain is a bit easier that way.
The road has a wide shoulder - albeit with thin bumps every 25 ft which I call butt whackers
That's from run-off.
One other thing to watch for are the RVs -- when those things spot a rest stop/lookout they barrel right for it running over whatever is in the way. If you hear one coming up behind, give it the right-of-way ... it'll take it whether you give it or not, and it is just more comfortable for you if you get out of the way.
