...is interesting. In the US, power lines are all very organized and there is rarely a power failure unless a power pole comes down, is knocked over by a car, etc.
I noticed that in Tokyo the power lines were a bit more chaotic...there were a lot of them bundled together. But I came to realize, and believe, that there was a method to the madness, and to trust that they would always be functional (Japanese efficiency being on par with the Swiss).
Conversely, when visiting Thailand and Cambodia, I saw the same type of power-line chaos, but within hours came to know that they indeed were not very reliable. In both countries, black-outs were the norm...
Either way, I took many photos of the tangled messes...I appreciated the patterns they made outlined against the blue of the sky...
