A trip that stays in my mind was a few years ago...
The road crosses the High Alps between Col de Lauteret and Valloire, if you put 45.052311, 6.393590 into GoogleEarth it should show the small layby where I parked to get the shot.
The road is not for the feint-hearted but well worth the effort, it nearly reduced caromac to tears being the passenger seeing the enormous dropoffs and lack of guard rails, but even she would do it again (with a little persuasion
)
If you look on Google Earth there is StreetView available so you can actually drive the route from the comfort and safety of your armchair :woohoo:
