I was taking a Flix bus from Brno, Czechia, to Linz, Austria, and this bus went through 3 WHSs (Trebic, Telc, Cesky Krumlov) and 1 TWHS that is Fishpond Network in the Trebon Basin.  I had been to all the 3 WHSs before on two different occasions. It seemed like groups of Chinese tourists were using this bus line to go from one WHS to another.

But I did not go into the town center of Trebon because the bus station in Trebon is a little farther out (500m?) from the center. 

Still, I was able to take this photo of Svet Pond, one of the 5 sites included in the nomination, from the bus when it was running on E49. 

I don't know the boundary of this nomination, so I'm not sure if I can claim that I was there, but I got to read about this site and understood the way the carps the Czech people ate on Christmas were supplied.  This site would be a unique one if it gets on the WH list.
