The "Wee mad road"
Probably the scariest road you'll ever drive in a big car, but well worth it.
This unusual web site might give you a "feeling":
http://www.theweemadroad.com/ watch the video, the middle of which is a short drive along the WMR in a "normal" car.
Note especially the road humps (sheep that DO NOT move) and the unforgiving stone walls.
And this will give you a flavour of the tarmac, note the telegraph pole siting in the photo below!:
