Thought I would post a picture of the horses on the beach. They just go where they will. The beach houses are build on stilts or the newer ones are elevated, because of the storms and high tides. The parking area for your house is under the house and when it rains your home does not get flooded.

If the horses decide they got hot and decided to seek shelter under your house, you just have to leave them alone. They will leave when they are good and ready. They are smaller in size, I suppose it is their diet. Good History about the wild horses. Found the history very interesting.
