A prayer flag seller beside the main road, seems to do a roaring trade

Prayer flags are printed pieces of coloured cotton strung together.  They are attached to temples and chortens, along mountain passes and streams. 

They come in sets of five one of each colour and are always hung in the same order.  Blue-sky, White-air. red-fire, green-water and yellow-earth. 

Tibetans call them Dar Cho.  Dar means longevity, good health, wealth and good fortune.  Cho means all sentient beings.  They blow on the wind harmonizing the environment bringing happiness and good fortune to all.

Three Australian cyclists, they had come a long way but look what lay ahead.  

One of these guys had been quite sick.  He decided to buy his altitude sickness pills in Lhasa only to find they weren't available.

I think this may be our first glimpse of Everest but so far away it was dwarfed by lesser peaks.  

Still a beautiful visa.
