Great road if you like twisty with a steep drop off on one side! :) Go slow and ignore tailgaters. It does get a little steep in spots too. If you haven't inspected the brakes on your FW in a while, now would be the time to do so...
Just so you know, hwy 199 is on the list of the most dangerous highways in the US. Myself, I'd do it again in a heartbeat if down that way.
