It made several huge switchbacks and sometimes we would see a truck far above, maybe three switchbacks away. This could be a little disheartening. For encouragement we looked down at the switchbacks we'd already done. At lunch as I cooked up some more hot muesli, we saw yaks climbing straight up steep hillsides and crossing the road. This amazed us.
Yaks look a lot more like cows than mountain goats.
How they can climb like that is a miracle. I got another flat tire shortly after lunch. This was truly bad news. It meant I really did have a flat tire disease. I was too weak to panic.
