Maybe it's because I grew up in the area and am use to the potential of 2' snow storms but I never understand the panic associated with them honestly. Before winter starts I keep old milk cartons and rinse them out. Then before a storm is coming I fill them up with water (just incase) and leave half of them outside to freeze (to stick in the freezer and fridge incase the power goes to keep things cool). So, I don't need to buy the overpriced bottles of water everyone fights over. Typically I go to the store 3-4 days before the "expected" storm and buy a handful of things: pop-tarts, bread, pb&j/fluff, and some fruit/snacks. Very basic items. I'm also an old time boy scout so I keep a bug-out bag handy with MRE's if it's sustained power loss. Say what you will but bug out bags take no effort to put together, take no room to store, and contain basic items most people use on a weekly basis.
But, I always find it hillarious listening and watching people panic and buy useless stuff they don't need. Some of the things I've seen bought that I really have to question:
Milk - It's extremely popular to buy milk before a storm but why? It's an item that needs to be in the fridge and it goes bad if you lose power for any extended period. You could leave it outside but why even bother. A couple days without milk won't kill you so why even buy something that goes bad if you can't keep it cold?
TV dinners - This confuses me on multiple levels. How are you suppose to keep them cold unless you leave them outdoors, how are you suppose to cook them unless you have a gas stove and manually lighting a modern gas stove might not be the brightest idea for most people unless you absolutely have to
Roman noodles - don't they need hot water? Again unless you have a gas stove which isn't bright for most people to manually light themselves or a fireplace you aren't going to get much use out of them
Ice cream - yes I've seen people stock up on ice cream, don't ask
Juices - see milk
Meat - if you lose power you're in trouble and that comes back to how are you going to cook it
Snow shoes - just incase it really snows 8' and you have to cross seas of snow to get help? (yes I've seen this)
At worst the roads will be bad for a couple of days why are you buying carts full of groceries in preparation for a long hold out. Does the snow bring zombies with it? Even if you lose power for weeks (happening a lot lately) resturants and supermarkets typically get power back quickly so there is always places to get food. I just never understand the basic panic that sets in with predictions of a big storm
