There are basketball courts all over the world, and many of them are located outdoors. Basketball is a popular recreational game at playgrounds, parks, or even in the street. A common problem at outdoor courts is losing a basketball; an errant shot or bounce can take a perfectly good basketball down a hill, into a neighboring yard, or into traffic.
Because of this inherent risk to outdoor courts, they are often enclosed by fences. This is especially true if the court in question is bordering other additional courts, as it minimizes the risk of another game being interrupted by a stray ball.
Some fences enclose entire courts or half-courts, while others are smaller and only exist to separate yards or houses. Fences can also vary greatly in height and material, based upon the resources available. Some also include net attachments to further decrease the likelihood of losing a ball.
