Pop down I did, and
here are some photos as evidence. (Viewing it as a set eliminates most redundancy).
Among features I did not photograph was a dance performance to live music. From the two examples I saw, the dance uses hands in much the way Indian dance forms do. One dance included three women and three men, the women all lined together on one side, the men on the other. They did not interact, and all performed the same movements, if not always at the same time. The four dancers in the second dance wore identical masks and robes. One dancer, because of his size, was clearly a man; the others were ambiguous. As in the other dance, the foot movements were simple, and in this one, humor played a part as the largest dancer ultimately became a sort of King of the Hill.
According to Wikipedia, 75% of the population is Buddhist, and several of the artists/docents noted that culture and religion are inseparable in Bhutan. Most spoke English fluently -- those who did not tended to be older. I asked whether Bhutan had ever been a British colony. No, but when the national education system was adopted in the 1960's, English teachers were recruited from India.
The Bhutan food tent offered a limited menu. My brother-in-law ordered the chicken flavored with lemongrass, I ordered some potato-onion-pepper concoction with cheese (yak cheese?), both came with red rice and we both shared with my sister. We all approved, even though my lunch became a bit too hot for my taste the more I ate.
And the weather cooperated nicely, thank you. The rain stopped before I arrived, and the heat rolled in not long before it was time to head back!
I didn't have time to check out the Texas or NASA exhibitions, although NASA dancers -- that could have been something to see!
