Las Vegas Pool Party Girls

Established in 1905, Las Vegas officially became a city in 1911. With the growth that followed, at the close of the century Las Vegas was the most populous American city founded in the 20th century (a distinction held by Chicago in the 19th century). The city's tolerance for various forms of adult entertainment earned it the title of Sin City, and this image has made Las Vegas a popular setting for films and television programs. On the other hand, Las Vegas also has the highest number of churches per capita of any major U.S. city. There are numerous outdoor lighting displays on Fremont Street, as well as elsewhere in the city.
The name Las Vegas is often applied to unincorporated areas that surround the city, especially the resort areas on and near the Las Vegas Strip. The 4 mi (6.4 km) stretch of Las Vegas Boulevard known as the Strip is mainly in the unincorporated communities of Paradise and Winchester, while a small portion overlaps into Las Vegas and the unincorporated community of Enterprise.
The major attractions in Las Vegas are the casinos and the hotels. The most famous hotel casinos are located on Las Vegas Boulevard on the portion of that road known as the Las Vegas Strip. These larger casinos are located outside of the city. Many of these hotels are massive, providing thousands of rooms, with their large adjoining casino areas. There are many hotel casinos in the city's downtown area as well, which was the focal point of the city's gaming industry in its early days. Several large hotels and casinos are also located somewhat off the Strip, as well as in the county around the city.
