Alcohol has long been part of the USA from the thirteen colonies to the Spanish American war which made the United States a world power and up to this day and age. But after the 1980's Alcohol was reserved for those 21 and up yet the legal age of adulthood is 18. I can understand making the Alcohol purchase age 21 to prevent 18 year olds from buying Alcohol for their fellow classmates who are 15 or 16 but what about going into a bar? Sure bars can be rowdy but can't we at least let our adult citizens drink. We can have them leave the bars at 10:00 or 9:00 PM if we must but we should not prevent adults who are under the age of 21 from drinking. Not in the land of the free.
