An all climbing day to get halfway up to Sela Pass. While Sangti valley was relatively warm, by the time we passed the 10 switchbacks to Senge dzhong, it was quite cool. We are all wearing coats by the fire inside Numu homestay. The homestay kitchens can be a very social place. Highway 13 is the main road to Tawang. It is presently being widened in some areas. Dirang is a super busy, super crowded little village, not really meant for automotive vehicles, but they are there. There are a few small stores for provisions. The day is a steady climb. Ours happened to be a bit slow with some intestinal trouble. Still the food is fascinating. Had a few momos. There were a few of the small, tasty bananas available in Dirang. We are pretty used to riding on the left side of the road now. By evening we have entered the Yak zone.
