It's a Rhode Island obsession; everyone goes out and buys milk and bread before a storm (or in the case of snow, before a possibility of a flurry).

The bread is so if the powah goes out, ya can make sangwiches. Not for nuttin, but, I dunno what milk'll do 'cept sowwah.

(I mean, if you're visiting, it's one thing, but if you lived here, your obsession with milk and bread would come back; you'd do what you had to do. And the wife says, "Hey, you know what? This coffee milk's too strong".)
