It is difficult to give a description of American laws concerning alcohol because they vary from state to state and city to city.
   Some towns allow the sale of very weak, 3.2 percent alcohol beer known as "three-two" beer. Some places do not allow the sale of any alcohol on Sundays, not only in bars but also in shops. You may find a locked bar over the alcohol shelves.
   In many parts of America, you are not allowed to drink alcohol in a public place. That is, you may not sit in a park or walk along a street drinking beer, and you cannot even take a nice bottle of wine on your picnic. In some public places, people can be seen taking drinks from cans wrapped in brown-paper bags. These are not cans of Coca-Cola. And in all states you are not allowed to drink alcohol while driving, or even have an opened alcohol container in the car. Some bars have a license only for beer and wine. Others are also allowed to sell spirits and thus, as Americans say, mixed drinks.
   Many bars have a period known as "happy hour", often longer than an hour, when they sell drinks with prices lower than usual. This is usually around 5p.m. and may be only on certain days of the week.
   Legal drinking age varies from state to state but is generally between 18 to 21. Some states permit the consumption of beer at 18 but spirits only at 21. Others permit the consumption only of "three-two" beer from 18 to 21. In any case, in some parts of the USA, young people are allowed to vote, marry, raise children, keep full-time jobs, be tried in courts as adults, join the army and even buy guns but not have a glass of beer. In some places 18 to 21 year olds are allowed into bars but not allowed to drink.
   Another even more interesting aspect of American drinking-age laws is that in some places people below legal drinking age are not even allowed to sell alcohol.
