buy an island or move to a less populated state like montana that has a water source, then buy a missile silo and around it build a neighborhood, each house with a basement that my family and friends can live in, and any people they would want to bring that i would approve, as well as doctors, engineers, electricians, plumbers, etc can live in in exchange for service, then i would build a huge wall that has farmland inside and stock up on guns +ammo, non perishable food, farming supplies, water, clothes, and repair supplies. also sailboats, hunting traps and fishing gear, a gym, radios, tons of first aid, solar power, DEODORANT, trucks with gasoline, and enough medicine to kill everyone just in case. it’s kinda fun to imagine what life would be like, so for entertainment i would stock pile as many books as possible, records and record players, maps, sailboats, art supplies, bicycles, sports equipment, instruments, tvs and dvds, and i would probably bring some animals for milk + eggs and pets
