Ha, I am actually really in this very delema right now. I live in an area expected to be flooded by the mighty Mississippi. Though my house is on stilts, I could still expect to be on my own for a substantial amount of time, and the water may still get it anyway. My contingency plan is to carry what I can to higher ground then put the rest up stairs and stay with it until the water takes it, or the water goes down. Since I may have to leave in a hurry, I am packing light and will need a weapon for self defence against Varmits of all kinds. After a lot of thought I broke it down to two, an AR-15 in .223 and a 1911 .45, along with an adequate supply of ammo, and a video camera. I also have a good boat and motor and plenty of gas. My primary concern is critters trying to escape the flood followed by looters trying to rob the deserted houses.
