A nursing home in Düsseldorf, Germany was having a problem with their Alzheimer's patients wandering off.  They would get out of the nursing home and try to return to homes or families that they remembered but no longer existed.  The facility came up with a novel solution; they had a bus stop constructed outside of the nursing home, complete with a bench and the familiar bus sign.  The only difference between this bus stop and others around the city is that no busses actually came to this bus stop. 

Since nearly everyone in Germany uses public transportation, the patients recognized the familiar sign and would sit to wait for the bus.  When a patient was spotted at the bus stop, a staff member would approach them and invite them inside for coffee while they wait for the 'bus.'  After a while, the patient forgot that they wanted to go anywhere in the first place.

Since few people in the U.S. are accustomed to using public transportation, the 'fake bus stop' might not work here.  Instead, here are a few suggestions for signs to place outside of a nursing home to attract any errant escapees.
