Just a heads-up, in case. A woman from the same group (at least, with a very similar spiel and documentation) came on–I think–Monday or Tuesday. Supposedly they are hired by an organization that gives them a chance to “get off the streets” and provides job training. The man (today) objected when I asked to take his picture–so I didn’t. He didn’t stop at any other houses on my block that I saw, but immediately headed off south. Maybe they are legitimate, and maybe not.
