You might have all of the physical items that you need set up for a bug-out scenario or a worldwide event, but there’s two major things that you absolutely need to discuss with your family and trusted friends before it’s too late: Your plan for emergency communications and where you all should meet up in case you get split up.
Should something happen and you’re separated from your loved ones, having a way to communicate (possibly without a cell phone or other form of technology) will help keep everyone from panicking and allow you to reconvene when the time is most opportune.
Likewise, you need to agree on a plan to meet somewhere specific immediately after an emergency event takes place. However, there’s always a chance that your specific location isn’t possible to get to - like if it is already taken over by an undesirable group of people or it’s physically blocked or guarded. Because of that, you should discuss more than one meetup location.
Without having communications or a meeting place planned, an emergency event could end up being an unnecessary tragedy - just talk it all out and make it a success story.
