"Why go to Mexico, when the US destinations are just fine and comparably priced "
Well intentioned drinking laws raised the drinking age to 21.
So now the students simply go to Mexico where its 18.
Just another example of the law of unintended consquences.
now instead of protecting "kids" from drinking, they go to Mexico where they are in much more danger.
But, the BEST part is now the parents go with the kids....and it's perfectly OK with the parents if the kids drink down there, because "Well, in Mexico it's legal to drink when you're 18. Oh, no, of course my little darling won't continue to drink when s/he gets back home."
Nothing like sending a mixed message, and don't get me started on "Why in the heck are parents going on a kid's senior trip????"
