Similar widespread blackouts also occurred in later years. One sometime in
the '80's (I can't recall exactly) and another on August 14, 2003. The root
cause of the 2003 blackout was a failure to trim trees along the power line.
This is something that could be even more widespread if the number of
transmission lines were raised an order of magnitude.

Later that same year, Italy suffered a wide spread blackout, suggesting it
isn't limited to just the North American power grid.
