True. But there need be alternatives to attending wild, drunken parties while underage for drinking. Maybe more sedate, alcohol-free events?
I was 18 when the legal age for drinking was 18. But I knew how to drink -- nurse a drink for two hours and get another, starting at 5PM. The drinks were likely watered down, anyway. But we college students had little tolerance for assault, violence, ugly language, or drugs (marijuana excepted). But we were college students.
But even if one is drinking age -- it would be wise to avoid wild, drunken parties, or for that matter, very rough bars.
Others didn't bother with the two-hours-between-drinks rule. They got sick.
Good. Paris is still a good tourist destination even if Tokyo is safer.
Or Syria. Or Iraq. Or Colombia. Or Venezuela.
As far as that goes, Detroit or St. Louis unless you really know where you are going.
