homeless ? I suggest contacting them and seeing what they need. You might be able to organize a collection drive for items they request.
There was a story in the local paper about a woman who had worked briefly at a homeless shelter and was inspired to start a faith based program in her home town. The director of a homeless program wrote a LTTE and suggested that supporting an existing program run by trained personnel would be better than misguided but well-intentioned efforts on one's own.
