Trollstigen ("Troll's Ladder"), you may remember, is that really bendy road in Norway. Something made me think of it today, so here are some related videos I found on YouTube:
Overview of the road, from above:
Blue tour buses (?) creeping around the hairpin curves:
(Glad I wasn't on one of those! Or worse yet-- one of the drivers!)
A couple of "race cars" driving down the mountain:
(Not as impressive as I remember it, because the camera never really shows how steep the drop-off is. And yes, this is both lanes; traffic going both directions has to share this road.)
This is what it looks like if/when you meet a car coming in the opposite direction:
And finally, a "transfer truck"-type vehicle trying to negotiate one of the curves:
(I wonder how he ever made it! What a nightmare!)
