What I notice here is Walmart and other lots are posted no overnight. But it appears there are a few likely homeless in older RVs staying quite consistently. I've seen one particular RV for months at a time, but not always there and never in same spot. These are fairly upscale locations 15 miles from beach. The parking lots are not impacting residences, they're too far away. At least my impression the stores and law enforcement tolerate this as long as it doesn't get out of hand (mess, noise, complaints). The other thing I suspect is some of these so called homeless people are not fitting into the classic definition. They appear to have some income, and living a different lifestyle. I suspect some have state park annual pass and migrate to beach (or other park day use) by day and back to these lots for the night.
