In St. Croix, one of the american virgin islands, drinking and driving is perfectly legal. I was shocked when I learned that from a bartender who encouraged me to take a beer with me for my ride home, an open one (I was driving).

Better yet when I asked her about if it was a problem having people drinking while driving she remarked that it was ok and safe because the roads on st. croix were so narrow and winding that people paid more attention and no one would speed.... didnt seem like the best of explanations to me.
