Nightclubs in America run the usual gamut of various music scenes, from discos with top-40 dance tunes to obscure clubs serving tiny slices of obscure musical genres. Country music dance clubs, or honky tonks, are laid fairly thick in the South and West, especially in rural areas and away from the coasts, but one or two can be found in almost any city. Also, gay/lesbian nightclubs exist in nearly every medium- to large-sized city.
Until 1977, the only U.S. state with legalized gambling was Nevada. The state has allowed games of chance since the 1930s, creating such resort cities as Las Vegas and Reno in the process. Dubbed "Sin City," Las Vegas in particular has evolved into an end-destination adult playground, offering many other after-hours activities such as amusement parks, night clubs, strip clubs, shows, bars and four star restaurants. Gambling has since spread outside of Nevada to a plethora of U.S. cities like Atlantic City, New Jersey and Biloxi, Mississippi, as well as to riverboats, offshore cruises and Indian reservations. State lotteries and "scratch games" are another, popular form of legalized gambling. However, online gaming and wagering on sports across state lines remains illegal in the U.S.
