Create a bicycle co-op, sponsored by the area churches. Have it function as a work/school facility for homeless youth. They could learn how to become bicycle mechanics. Run a special workshop during the winter months, where the homeless youth learn how to tig-weld frames and make custom bicycles. The head of the co-op, should be someone like a teacher, minister, counselor, or police officer, who knows bikes.
This will be more of a permanent fixture within the community that can offer real help for the homeless youth of our society. At the days end, they can clean up the co-op, prepare own meals, study (if they don't have their GED's), and retire for the night.
