@mysteryman,
For mentally challenged individuals this is what coops and rooming houses are for. We already have them in the city I live in. Rooming houses filled with handicapped people. I might add, have you never heard of nursing homes and ombudsmen? Well, same idea... A logical and easy solution when one's concern is based around the already born when billions are spent by the republicans and religious right to protect eggs.
There are many who would like to remain homeless but at night they still need shelter from the elements, a shower, clean clothes and three meals a day... I know this first hand because I spent two years homeless myself.
