The question seems open to interpretation (which is bad for surveys like this).

If I visit a location that was the site of a mass shooting a few years later, have I been “physically present on the scene of a mass shooting”?

I think you could reasonably answer yes: you’ve been to the physical place where it happened, even if not at the time it happened.

This is why it’s important to operate with enough available reserves (fast and slow) to cover the unexpected loss of your biggest generator, transformer, and/or transmission line.

Their black start procedures are going to be getting a good workout; I hope they’re well tested.
