Which is fascinating, because when I was a kid the drinking age in some places in America was still 18. It had always been 21, but the protesters against the Vietnam draft made it a big point that they could be sent to war but weren't allowed to drink at home so states lowered the drinking age to 18 through most of the 1970s. When I turned 18, Las Vegas and New Orleans were the only places in America that still had that law in place, and since then they both reverted to 21.
