So, seriously, you’re in the middle of this and you are fully aware that you must get water, food, shelter (which may be a blanket). Are you going to patiently wait for the rescue planes? Before you answer check out the logistical problems the rescue people need to overcome to help just a few. It may be weeks before you (and they) will get water, food, tents. So really, you’re going to wait?
First of all, I am prepared so I don’t have to loot or scrounge. Secondly, I work WITH friends and neighbors to provide security for ourselves and others. Then I work with them to assign priorities for the sharing of whatever supplies we all have. If no one wants to do that I walk out and keep on walking. I can live off of the land here, by myself, just fine. Those who want to go rogue had better like the taste of hot lead.
