On a good day, anyone can lead a trek group. But the best ones actually show their mettle when things start to unravel. In our group, one of the participants became quite unwell (happens pretty frequently in high altitudes) at Gorakshep. And then at Lukla, inclement weather delayed our departure. Dawa, at each of the instances literally moved mountains to take care of the group. Suffice to say we are now friends!!
