This is one of the few times I like the color image better. Did not expect the green strips. Since this is Region B, I assume that the water flows left to right?
Yep, color works here, especially as Martina is so careful with the dosage.And, Jeff, my guess is "right to left" here, which better explains the inclination of the buoy.---A 2nd try, and I do hate google's cookie heap I have to accept just for commenting :(
Jeff, Markus - now things are getting complicated: this is a "Fahrwasserteilungstonne", see B.13 here http://de.wikipedia.org/wiki/Bildtafel_der_Binnenschifffahrtszeichen_in_Deutschland Markus is right about the direction. Let's see if I simply can show it on google maps (sorry Markus) : http://goo.gl/maps/Qiz9u
