I'm a "profesional" youtube consumer as not one day goes by without spending at least one hour watching videos. I had the pleasure today to find, as a random recommendation, the video of an American couple presenting Romania. In fact they actually recorded for more than 10 minutes the Danube's area close to where I live and they seemed to like it more than I do 😁.
Have a look if you're interested. Sailing allowed as well 😁 and the scenery is pretty nice.
