Check out Family Promise in the Mat-Su.  Only some churches are suitably equipped to offer overnight housing for families in need, but they have volunteers, including many from other churches, that help out.  I'm sure you'd be welcome to contact them to learn more. There's an annual cardboard box camp out to raise awareness and funds, and, aside from being fun, the presentations are generally both informative and uplifting. It's really nice to see people that just needed a little help to get back on their feet. No doubt that some of the homeless have issues that are going to be more challenging to deal with, but it's worth a try to see if there are constructive ways to address them.
