Happens here almost daily.
You’re in Mississippi?
It sounds like things have already gotten crazier than I knew. When did this start? I live in a red region surrounded by a sea of solid blue. Of course, part of the daily landscape is scary-looking people holding up their cardboard “will work for food” signs on street corners and off-ramps. But I’ve yet to hear of any of these wastrels and frauds actually going door-to-door here.
I’m surprised by these reports, but forewarned is forearmed.
I’ve read that the “hobo signs” are becoming more common again (last time this stuff was really seen was before WWII). Back then, they’d use cryptic markings to warn of danger, indicate safe routes, etc. Do a little research on the symbols they use and then look around your property to see if you’ve been marked as a “soft touch” for handouts.
