Yet the even more interesting part was found in the sidebar - videos featuring the TAO offices within the district. The one embedded here is from Kurukhu (องค์การบริหารส่วนตำบลกุรุคุ).
As leknkp uploaded many videos, I have collected those on the TAO offices in a playlist, 23 videos including a few from other districts. I haven't yet seen them all in detail, which I really need to do - for example the video on At Samat shows a table with the past TAO chairmen and mayors as well as chairmen of the TAO council - data which I could not find on the website of the TAO. And I also want to find the offices in Google Earth, while it is easy to recognize the building with the help of the video, the difficult part is to know where to look - sadly I cannot find any geotags within the videos.
Another interesting video by leknkp are an interview with a TAO mayor in Na Kae district, and I am sure there are more I haven't spotted yet.
