That's what I'm thinking also.
How would you take the Kiel Canal at nite with no lights as an example?
And as metal and such became harder to come by?
Why KEEP the lights?
Details are hard to actually find because who would document EVERYTHING about EVERYTHING at times like those?
There's probably information somewhere but more and more information is being hidden away to pay-to-use sites now days.
The days of free information on the 'Net is getting dangerously close to an end.
