Caught up with a guy who has just recently come back from the same trip that we are taking. He said altitude sickness got to them all in varying degrees and one of the team bailed out. He found the Rohtang Pass to be the most treacherous part of his trip (photos following). No worries re bike mechanics though. One of the Lee Enfields in his team bent a valve, and a crowd stopped to help. The whipped the head off on the side of the road, bashed the valve straight with a hammer, reassembled it, and it actually ran fine thereafter. I’ll be buggered.
