Preppers’ PING!!
I live in small town USA, in a rural county. Most people only travel into town once a week for groceries-some less often.
Most people I know can make it quite a while on their own. We have had lots of power outages, tornadoes, and other natural disasters - many lasting way longer than 72 hrs.
So far, none of those have led to widescale rioting or looting like this. All we ever have is the usual criminal element occasionally engaging in breaking and entering etc.
Could be that generalisations from urban areas don’t translate well to rural areas.
