Adam Riemann of Motology shows us a motorbike ride down a particularly hairy mountain trail. It's part of his movie 'Himalayan Hero', documenting a father-and-son ride of 4,500 kilometers (about 2,800 miles) through the Himalayas.
I can't help wondering what normally uses that trail. It's certainly not wide enough for full-size motor vehicles. Yaks, perhaps?
