The beach is a very specific environment, with its own activities, rituals, and unique style of dress. It's a worldwide, culturally modern phenomenon. The beach is a place everyone goes to, from the richest people and families to the poorest. There is an entire industry and lifestyle built around these narrow strips of sand edging the ocean. Some of the most expensive real estate in the world is beach front. There are resorts, islands, and thousands of miles of coastline given over to leisure.
