Slight change of summer plans, probably a prudent one. Instead of going to Kailash via Lhasa from Shanghai, it looks like we're doing the tried and truer ascent from Nepal. That will give me a bit more time to get accustomed to altitudes... though the Kathmandu Valley's 1400 meters are as nothing compared to our trek from 4640 as high as 5630 meters. Insanity! I fear my head will explode, or float away! So the rather ridiculous China-Tibet-India trip is giving way to something more localized. I might still be able to go to Lhasa afterward, though.
