If you have pets, make sure they have food and water.
If you have a wife, make sure she is taking care of the kids.
Don't go out stocking up on milk, eggs and bread. If you have no power or heat, the last thing you want is warm milk, raw eggs and bread.
Do what I did. Oreo's, Chips Ahoy, anything Entenmanns, plenty of beer [Guiness is not bad when served warm].
Oh and I heard batteries might come in handy too :)
