Are you shitting me lj? insensitive much?
Around here it appears peoples favourite snacks are: meat; veggies; bread; uht milk; baked beans; and bottled water. Oh, and toilet paper. Even in my relatively dry suburb people have been panic shopping and many of the shelves on the local supermarket are bare. I guess people are preparing for the more subtle second wave effects of the soggy apocalypse, e.g. loss of power and difficulty of goods distribution. I have been told by a survivalist friend that our city's supermarkets only have enough standby stock to feed our communities for 3 days.
Interestingly, apart from the mass purchasing of baked beans and ready made canned meals, there seemed to be ample supplies of tinned legumes (i.e. lentils, kidney beans etc) and other tinned veggies--the very things I think will be the most useful if people become isolated without power. It looks like as a gluten free vegan I win at panic shopping :)
