Here is the wiki link, it is Hwy 17. It is not a Truck Friendly road at all, which is evident if you do a search and then look at the images tag, all kinds of truck, and car wrecks along the road.
and a google image search link I hope that link works for you it did when I clicked it.
Well, I'm surprised that I've never ridden it. I'll fix that oversight before too long :) Looks like my kind of place!
I've been close several times but never right there. Amazing. Thanks for a really great tip for me!
