I am making extra ice and putting it in baggies ready to go into a cooler. Have tuna, canned tomato soup on hand, some canned fruit. Evaporated milk. Lots of peanut butter and crackers. Water. Wet wipes. (Not food related, forgive me, but batteries, radio, candles, lanterns, cat carrier and her food ready.)
For heating food, have lots of charcoal for our trusty Weber, sterno for fondue pot.
Planning another grocery store run as necessary, what would you get?
