from this article:
It’s called Family Promise of Tulsa County, and it’s built on a simple idea: provide food and shelter for homeless families in Sunday school rooms or other church rooms that otherwise would sit empty during the week. ... He said no matter how ordinary a church building is, “It is still better than under an overpass. It’s better than a cardboard box.” “I would encourage everyone to try it, because your small storage room is more safe than outside in the rain and the snow,” Turner said.
at first i didn’t understand the rotation between the churches, but after reflection I think it has benefits:
each move encourages lean living, as everything must be relocated
offers a weekly opportunity to graduate out of the program
keeps it from becoming a squat
