I recall a few visitors at work that asked 'Where to buy liquor' and I told them it would be quicker to list the places that you can't buy liquor.
Can't stomach a Daiquiri, but you have to appreciate the drive thru Daiquiri shops.
Hell, for a good while you could buy beer at 18 in Louisiana but the drinking age was 21.
You can still go into a bar in Louisiana with your parents/guardian and drink at 18.
