In my little town, the St Patricks Day Parade starts at about 7am and the bars open at 6:30am. My neighbor owns the main bar in town and he said they sold 350 bottles of whiskey St. Paddy's morning. Just shots.
That's a lot of Irish coffee!
Even when I drank heavy, I never liked St. Paddy's day all that much. It's almost like it was too much booze, even for me
