Genset, water reserves, lots of guns, and liberal anti gun Mormon neighbor who has it coming!
Genset? Works fine until your tank runs dry. How long is that? Days? A week or two? If you have a large tank, how,do you prevent the fuel from deteriorating?
Might I suggest a small solar array. A small system can be reliable and cheap. Although lights and power can be a blessing or a curse.
If you have power when most everyone else does not.... Desperate people do dumb things. If you live around “gibmedats” like I do. Have a plan for them.
I don’t worry about my neighbors next door, but three blocks away. We have discussed what would happen if they decided to try their hand at take sh_t from whitey.
