There is not going to be much grouping of anything in the city or rural areas. I have actually lived through Martial Law during a natural disaster. I have lived in a rural community when there was dwindling resources. If you think people are going to share with you think again. If you don't have your own food your not going to be any better off in the country than the city. People are all the same no matter where you go. At least in the city you can blend in and dissapear while your operating. It's harder than most think to disapear in the woods against technology and Elite teams with trackers.
