Today, I came across this jewel on the continuing investigation of last August's blackout in the Northeast US and Southeast Canada.
This is worth noting for two reasons. First, it's just plain interesting. If you have any curiosity about the world that surrounds you, this is good stuff to read. Second, it's a great example of just how vulnerable our modern/high-tech systems are--not just to Mother Nature or those who would deliberately damage them, but to our own sloppy work.
I hope it makes you think a bit about preparedness. You should be ready for bad times--they're a commin'.
