I've been putting together a 'stash' over the last few months.
Stuff that gets used anyway, so rice, pasta, lentils, oats, tins of soup/fruit/veg, some bottled water, toilet paper etc.
I'm covered for the next time we get snowed in, the water is off for whatever reason (happened a few times in the last couple of years), delays in supplies getting to the shops, job loss, or just plain feeling unwell and not wanting to go out... short term emergencies.
I'm not preparing for armageddon, nuclear war, EMP, zombies, or anything else people may have heard mentioned on any Doomsday Prepper type American TV program.
We had issues earlier this year with the snow. There were really only two/three days of the main roads being closed with no deliveries to the main shops. Still bread and milk became unavailable almost immediately, ALL (tin and fresh) fruit and veg followed soon after, and stayed largely unavailable for about a week. Ingredients for baking your own bread etc were also all gone and took time for supermarkets to restock.
This was in central belt Scotland, not some remote area.
It's not ridiculous, or hysterical overreacting to have a supply of food and other essentials available at home.
