I actually don’t seek them out.
The first rule of figh… err, prepping is don’t talk about prepping!
Seriously though, if it were to come up in conversation I’d entertain exchanging info / plans.
It isn’t something that lends itself to most standard conversations though.
I should say that I have as much as possible weeded out all conservatives from my daily interactions, as I just can’t look past their goals of making our world a more hateful and miserable place.

So, my prepping talks are typically kept online, and anonymous.
