Honestly, knowledge of how to make/do things without modern technology is the best prepping you can have.

I have not come into contact with a lot of preppers, I must be honest. All the ones I've seen on TV are the 'bad rep' preppers that are just... mor dakka. Even the show displaying their lifestyle choice encourages mor dakka.

I'm not in favour of Mor Dakka Prepping. It's a silly way to try and rebuild the world. At least there's some people who realise that they're not an island.
