1. Nobody needs to know about your cache. Period. If, God forbid, you ever need it, it should surprise even your spouse.
2. Nobody needs to know all your plans. Family members only need to know those parts that depend on them. Friends and strangers should not even know that you have a plan unless...see the next point.
3. Nobody gets "cut in" until you have evidence that you can trust them with your life and your future. This includes everyone, even family. Some "like-minded" dude you met in a bar a year ago does not cut it.
4. Leave play-acting for the kids. Answering the door geared up like a ninja is just plain dumb for anybody. Keep it handy, but keep in SECRET.
In summary, give no one a reason to think that a SWAT team would be anything but bored to death by a visit to your house.
I want to echo Jboot’s comments. There are lessons learned here.
1st Rule of Prep Club: You do not talk about Prep Club.
2nd Rule of Prep Club: You DO NOT talk about Prep Club.
Be careful what you say and post on social media. Just because you are in a "room" full of like-minded souls, always assume that your words will be read by the authorities.
