Awesome pics again, Rick!
Glad you enjoyed your holiday. I am reposting this one as well!
As for the beach sand, yeah, it must have been trucked in. In Vienna, along the Danube Canal, we have a few places where they did the same, to give it a exotic vacation look. One of the places I like to go to there is Herrmanns Strand Bar - here are a couple of my own pics from May 2019:
Another place, along the Danube, is the "Copa Cagrana", a whole stretch with lots of beach bars and restaurants. While the Danube Canal is a side arm close to the downtown area in Vienna, the Copa Cagrana area is on the north shore of the Danube river, or as we call it 'Transdanubia' (I live on that 'other' side of the river). But the actual Transdanubia is in Hungary, we just 'borrowed' the name, same meaning 'the other side of the river'.
