How about this for consideration, a few years back when the Delaware spilled it's banks along with the other creeks and streams in the area.
I was sleepin' when the phone rang about 5:30 am, it was my neighbor from a mile down the road, (my street is 2 1/2 miles long with a stream/creek zigzaggin' across the floor of the valley I live in. The phone call was to alert me to the fast risin' waters and the mud slides that were startin' to block the valley in.
Now I don't know why but of the 10 homes on my street 9 of 'em had no power, phone or cable, my house was above flood stage and I had all the amenities a home owner could want, along with 25 people who had none of those things also in my house.
My home became a command center for the street as wifes contacted husbands and other family members to notify them of their where abouts and condition of their houses.
For three days every inch of my home was filled with kids, pets and people, lucily we had two grills and lots of coolers along with one freezer and two refridgerator/freezers, three bathrooms and well water.
We took care of everyone till they could either get back home or to a family members house.
My point to all of this is suppose they all come to you with their food and supplies, is there a BIB, (Bug in Bag) for when ya gotta stay home and help the neighbors and extended family?
Every SHTF scenario is gonna be different and priorities reestablished as needed.
I didn't expect all those people in my home but when they started showin' up I did what had to be done, now if I lived in the inner city and all my supplies were all I had, I might think differently but then I'll address that situation as it arises knowin' I'm capable of doin; what ever is called for.
