Yes I do. Water is very fluid. If it makes you feel better, I can say you are correct.
The intent of the topic was more about finding water sources behind the Pyramids, than drinking from the Nile.
I am faced with more important issues right now. I want to drive for 6 hours up the Coast, and question will the gas stations still be open, there and when I return in a week.
Do I want to use roadside bathrooms? They just closed down two Coastal camping grounds here in Oregon, due to corona. A tree is good for me, my wife is not so happy with that example.
You take care of yourself.
