Tip of the hat to Utahans for choosing not to interfere with people's alcohol purchasing/consumption decisions, even if most of them don't touch the stuff themselves. If only the Baptists had such consistency.
What about WV and LA?
Can't speak for N. Louisiana (though I'm certain it's all wet) but the south part of the state and the New Orleans area in particular have incredible minimal laws about selling alcohol. Louisiana was also the last state to raise the drinking age to 21, and only did so because they would have lost road money from the Feds--Reagan blackmailed the states into raising the age.
I actually turned legal three times in my life, 18 in Louisiana, 19 in Texas, and 21 in Texas because Texas was such a dick of a state that when they raised the age they didn't include a grandfather clause.
