9th highest pass in the world

"I did it by bus, on my southamerica tour and the bus driver lost control, and jumped outside. We almosto died. I rather prefer the bike"
ha, ha, imagine bus is going apeshit and driver jumped out of the bus. luckily everything was ok for us, but we were scared like never before.
