If I were in a city of comparable size to NYC, I would hunker down for a few days in hopes that the panic would subside and the roads would be cleared of the ones who didn’t prepare and merely panicked.
You beat me to it.
I don’t live anywhere near NYC ,but that is primary — to bug-in. Bugging out would be a very dangerous thing to do no matter where you live. I would only do it if the alternative was much, much worse.
