I'd love to do that one. The wife and I did the Rome to Sicily a couple of years ago. Like you said, expensive, but the best vacation we've ever had.
Those switchbacks reminded me, I'd never ridden anything that tight and the first couple of days I felt like an idiot. After a few days I started getting the feel for it though. It's a totally different world from Texas.
Craig, you need to join us next month for the ride to the Dragon. The roads there are just as good, maybe better!
