Back in 2006, I wrote a Newsweek article about the problems that warm-weather cities like Orlando and Las Vegas were having with their homeless populations, and the rather creative methods they were using to control them -- namely banning public feedings and consigning all panhandling to 3-by-15-foot "panhandling zones" painted on sidewalks.
Turns out the solutions have only gotten more creative in the last few years. The newest innovation are "homeless meters," repurposed parking meters — painted a different color and set back from the street — that people can deposit coins into rather than give spare change to panhandlers. Cities then donate the collected money to nonprofit groups, which in turn use the funds to buy things like bus tickets. Advocates say this cuts down on the abuse of funds, and ensures that donations are put to the best use.
