This is a great question. We had a bit of a conversation over dinner about this yesterday after you asked,
@rlm . All in all, I would say that while it was tiring, it was doable. The "advantage" to regional outages like this while living in a bigger city is that you may have multiple alternatives for where to find power, internet and other essentials. Also, water was not affected; it would be much more difficult had we had to melt snow or so to get water.
There is no "worst" part for us really this time around. There were inconveniences, but they helped reflect on our dependency on certain things and how we expect them to be available.
The part I felt worst about is losing about a half day of work, about possibly not being reachable for colleagues and family. The situation certainly affected sleep and zapped away a lot of energy (pun intended) and there were some personal projects/passions that suffered.
The biggest financial loss will be the following trimming/felling of some of the trees in our yard. It's nice to have trees, but it's a lot of expensive maintenance. We also had to shoot out some food from the freezer, since there was no time to cook and store it all before it went bad. Not worth an insurance claim (due to the deductible), but definitely a pity.
