Sounds like good suggestions.
I live alone and have given up trying to work with anyone else. Friends and neighbors do not believe that more than a few days food is needed in case of a hurricane. They are just in near complete denial of world conditions.
Local group a year or two ago said they were starting a team to work together. I thought it would be good for me, but first thing they did was put an age limit on it, so I said ... to myself, “It is their loss”. “I have some very good skills to share”.
I now plan to just go it alone. It has cost a lot more, but I seem to be about ready. I guess we all keep reading and adding to our plans.
IOW, the group would quickly turn into a death panel. Good thing you found out ahead of time.
Most of our neighbors are loony tunes but I have my eye on the one who fly rebel flags and the repair guy. When we had prowlers, the 80 year old widow lady was out guarding her place so no question I’d take her over the wimpy guy who wouldn’t even turn on his outside light.
