Curly Brunette Girl Shows Off In The Backyard

While many properties accessing directly onto a street or an access route to a property may not have a front garden, virtually all will have some space at the back, however small, the exceptions being back to back housing common in northern industrial towns in England, for example.
A front garden is a formal and semi-public space and so subject to the constraints of convention and law. However, the back garden is more private and casual, and so can be put to more purposes.
