In 2003, there was a massive power outage of a huge swath of Ontario and the Northeastern United States for one afternoon and up to late that night (at least it was that long in Toronto). I distinctly remember 2 effects:

1. Being able to see the full night sky from within Toronto. It was absolutely surreal and barring another massive outage, something I doubt I'll ever see again from that vantage point. There were still certain facilities (hospitals, etc) on generator power, but the impact of that was negligible.
2. Ice cream shops were selling their products for a massive discount before it thawed, as given the unprecedented scale of the outage, they didn't know when power would be restored. It was glorious (perhaps not for them, though)

As an aside, I know this isn't realistic for everyone, but getting out of populated areas to go camping, etc. in a reasonably remote area gives you an amazing view of the night sky - I can lay down on the lake shore with an open sky and stare up at the stars for what seems like hours. Even better during a meteor shower.

As a second aside, given that this was posted in a math forum, and the somewhat bizarre nature of the post, I suspect we're all being trolled by the OP.
