I am housesitting a beach front home for a few days while the owner is out of town. Yesterday, a family of four parked in the driveway, out of sight from the street, proceeded to ring the doorbell (caught on camera), discover that nobody was there at the moment, and proceeded to help themselves to the walkway around the house, the walkover, the dunes, etc before they got to the beach where they enjoyed the beach for an hour and a half or so. When they headed back up to the dunes and my friend's walkover, I asked them where they were going and they replied that their friend (who was not my friend/owner) told them they could come there to go to the beach. I directed them to the nearest public beach access a short walk away. Things like this just might be part of the reason that beachfront owners around here are frustrated. I can honestly say that I have never had anything like this happen at my inland property.
These type of things happen much more frequently than you would think. It would be an eye opening experience to visit a beachfront home for a week during the peak of tourist season and see some of the things that go on. Really love the folks that think it's okay to climb up on your walkover and watch the sunset. It's a little unnerving when you walk outside your door and there are strangers sitting there.
