What I used to do on St. Patrick's Day:
(How real an "Irish pub" is J. Patrick's? One year, I spied a young woman adding blue food dye to her Harp to produce a green beer. As she went "Wooooo!" and others averted their eyes at the travesty, I politely took her arm, put down her beer, said "C'mon, out. Out, out, out!" and pushed/dragged her out the front door.
The spectators cheered me. We let her back in, but our point had been made.)
What I intend to do tomorrow:
Hide. Hide more. Then make my way to The Barns of Wolf Trap for a concert by Scotland's greatest folk music band, Battlefield Band. At least Wolf Trap has some decent beer--and I'll wager none of it will be green.
