Whiskey loves its firsts. From the first person to char a barrel for aging, to the first mention of whisky in the exchequer rolls, there seems an obsession with finding out where things started. And they are usually positive subjects. But what about something like Prohibition? Which was the first state to go dry? That question raised its head when I heard about a famous shootout that led one state to jump to prohibition a full eleven years before the Volstead Act. Were they the first? I'll investigate, in this week's episode.
