I would put a big spray painted sign on the out side of my house. "IN NEED OF FOOD - PLEASE HELP" I would hide all the food as best I could so the inside of my house already looked rampaged. If someone rang my bell I would answer it. If someone started kicking at the door I would shoot one in the floor. If they kick again I would put 2 in the door. Fill tub and all but one sink with water. My house is brick so I would only need to fortify the doors and big windows. Set up my portable HAM radio and my Base ham. I would have to setup an indoor antenna system because I don't have one up now. My boiler is a coal conversion so I could pull out the burner and heat my house with wood if I had to. My tenants and I are all shooters so I would distribute appropriate firearms and set up a lookout schedule. I would try to help who I could. For instance. I have chlorine tablets each one will make 1000 gal of water drinkable. I would give out a few of those if needed. As far as food goes. I am Italian and have quite a bit of canned goods, pasta, rice, flour, beans, sugar ,etc. I have a nut tree in the back yard and I have fat squire living around my house and plenty of little shit birds. Next, I would be trying to gather info on the situation and condition of my family via HAM or internet or cell. I also would monitor public service and MARS radio. There is a really old lady that lives across the street. As much as i wouldn't want to live with her I might bring her in as long as she had some food etc.
