This cat had better be wrong.
He’s not, I’ve been tracking it too. Plan on a garden with heirloom plants, even if you have to do container gardening. Learn to can, alternative heat. Filter water, standard live off the grid/EMP stuff. Ammo, Weapons, non power tools. 100% USA MADE https://tarterusa.com/ BOTTOMLESS horse troughs, fire rings, and where to find a dealer. Water collection.
Our soil is junk, we use containers. Pest control for the garden. Found fungus control doesn’t work well. Lost 200 strawberry plants to one.
If you think TP was a big problem food, electricity will be worse. No freezers yet except a few small Chinese pieces of junk. Gas of course will be a issue, BBQ grill charcoal or propane to cook on. Get before inflation hits.
I do the grocery shopping and meat, canned goods are already short, pet food has gone out the roof price wise. Sales are like buy 5 boxes of easy to go stale kiddie cereal doesn’t work for 1 person. Or shelf is empty odd brands you have no idea of quality/taste. You will need basics for baking, seasoning. Rotating your stock is a must. Rice, pasta, dried beans, store well in 5 gal labeled lidded buckets. Look for long term storage items that don’t need a fridge.
Bigger issue is fresh stuff. Milk, eggs, bread, dairy that don’t store long.
