  Turning 21 is a milestone for most Americans because it marks entry into adulthood. Though age 18 is the age of consent for many things, turning 21 means a person is of legal drinking age and can enter nightclubs. Though not everyone is racing to take a drink when turning 21, many individuals choose to celebrate the occasion by planning parties in places where there is access to alcoholic beverages.
