Sportsmanlike behaviour in the modern age?

That IS weird! 🤣

This is "Single-Bamboo Drifting" (独竹漂), a traditional sport of the Miao peoples in Guizhou.

You stand on a broad bamboo trunk and steer/propel with a thin bamboo stick. Often combining it with complicated dance. It requires a lot more balance than I could ever have managed at any point in my life.

Judging by later messages, this is a True Believer. Which when translated to English is "idiot".

You seem both nice and very bright.

I think you will find that traditionally they do anal probes for this.

Seems like military drone tests in my opinion.

Have any actual expertise to back that opinion up?

(Hint: probably not.)
