Basically, I haven't done so yet, but I need to get serious about storm preparations tomorrow. I'm in Philly where we expect to get hit hard, and my wife is 9 months pregnant.
We're electric everything here without any gas backups. I'll run out tomorrow and grab propane for the grill, and I've got charcoal and cast-iron, if I need it. We've lined up a generator rental, since we can't find one for purchase, and we're discussing if we want to go forward with it. More likely, I'll get myself an indoor-rated, portable propane heater and some extra tanks.
Not much in the way of dry and canned foods, but I'll pick up what I can tomorrow at the store. Perishables tend to go quick, but the items that actually matter such as cans and UHT pasteurized products, don't go quickly at all. UHT milk will stay good on the shelf for >6 months. Plus, we have enough to last us the next week if I rationed (my wife can't, being pregnant)
Overall, not prepared, but will be... I hope.
