I think of preparing for a disaster (stay in place) as something temporary like the electricity goes out for a few days. We usually have some water, juice canned and dry goods in our pantry. We always have candles on hand and a battery powered lantern. After that everyone would be on the move and it wouldn’t be safe to stay put.
I watch doomsday movies like Greenland & Outback (communication is key so you need sticky notes, a sharpie, belt cutter, in addition to a car survival kit) and The Walking Dead.
We could survive a few days staying in one place but any longer you can’t stay where you are and keep food/water to yourself without being heavily armed.
So I prep thinking about being on the move without a car and living off the land so shelter (waterproof tent, warmth (emergency blankets, gloves, fire/portable hiking utensils, dehydrated basics and a book about plants (what you can and cannot eat).
Knowledge is power so watch survival videos: thinking I would need Chlorine tablets (toilet tank and water heater water; pond), portable stoves (we have gas but what if that goes out), basic hygiene (tooth powder, body wipes, washable reusable feminine pads, know how to make your own soap), flashlight and candles; radio, solar powered battery charger. First aid kit with bigger bandaids, emergency wound closure stitches; tourniquets (cuts are more likely to be bigger), anti venom?
In our home I keep a fire escape ladder, small fire extinguishers (kitchen and 2 rooms) and fire blankets:

Edit: forgot coffee (very important to stay alert but hydrated); some good bug spray/sunscreen would be great as well.
