Camping is an outdoor activity involving overnight stays away from home, either without shelter or using basic shelter such as a tent or a recreational vehicle. Typically participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment or an educational experience. The night (or more) spent outdoors distinguishes camping from day-tripping, picnicking, and other similarly short-term recreational activities.
Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. Camping is a key part of many youth organizations around the world, such as Scouting, which use it to teach both self-reliance and teamwork.
Here is a set of vintage postcards that shows camping in the United States in the 1950s and 1960s.
