I guessed that if nobody else cared about this, you would, Dennis.
I always wanted to do the drive to the Keys, but never got that far South the times I was in Florida. I used to love the interchanges on the newer freeways in SoCal.
The route we did the other day was excellent. The part between Porlock and Leymouth was, as the article said, the best bit. Really steep hills at each end, and then great curves and inclines along the way.
At one point, there was a steep drop to a crevasse on one side of us, and a steep drop to the water on the other. Absolutely stunning and great fun, even as a passenger.
It also had lots of no restriction zones, so we got to see what our car could do. (Of course, now it can't do anything until we get a new battery on Monday...)
