Amazing piece !! So happy to find this and you! I'm in Portugal, but am very like minded in everything you said.. I would love to start a group like that here. There are a few I know of bit far away, about an hours drive from me, which is a bit far if there are no cars and I can't go on the roads , so I'd like to find something closer.
You've inspired me to try the same.
If you would be comfortable sharing any information, maybe through telegram, how did you organize? Was it totally offline? Are you using secure networks? I'm a total noob with that level of tech savyness, but would love to learn to the skills to communicate and organise away from prying eyes and ears..
