Been looking at the light pollution maps. Someone has massaged them big time.
Just a for instance take Egypt which I can personally verify.
The whole length of the Nile in Egypt is as bright as London on the map , has nobody questioned this.
I have been on a 4 day trip from Cairo south to Aswan 300mls approx, and believe me at night the whole length of that journey, once out of Cairo was pitch black at night.
How can we believe the rest of this map, who would or why would someone do this?
Comment on this please gents.

Can't - no map. You should have provided a link.
