The "Blue Danube"

 There is a song about the "beautiful Blue Danube" Well we experienced the Danube to be more "Brown" than "Blue" I am sure with all the rain we had in the last week it added to the water being more brown from all the run off.
However I think this picture reflects the sky in the water and it looks pretty nice and blue!
So we can still sing about the "Schöne Blaue Donau"

. 

Every boater in North America knows what "red on right returning" means.

That would indicate ( in these two pictures) that we would be going UP stream.... However this rule is just the opposite  in Europa and red is on the left when going up stream ( returning)
