And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Strait of Gibraltar. Embiggen for more detail. Interesting where the rivers run into the sea.
There is a photograph in some journal of the Detroit River as it approaches Lake Erie. The suspended silts and clays reveal that there are actually 7 (?) parallel streaming flowing in the channel.
There is another of the Connecticut River on the cover of the Journal Water Pollution Control Federation showing a sewage discharge and two merging tributaries also flowing in parallel, unmixed.
I used to show them in my hydraulic classes when we discussed mixing. But that was 20 years ago, and I lost the references.
I have been lucky enough to have gone to The Rock twice now. It was for me one the nicest places that I have been to while in Europe. If you get a chance to go then do so!
Tablet can't tell river's well will need to Google Earth for that, but fascinating the snow on the African side.
