Calling the problem damn near out of control, local farmer Cliff Contreau confirmed that the 125-person wedding reception he chased out of his barn Saturday evening was the fifth such wedding party hes had to scare off his property this month. They come in here almost every weekend stringing up incandescent light bulbs and taking photos next to my hay bales. This is private property, for Petes sake! said Contreau, 63, who added that he now instinctively reaches for his rifle any time he hears a string quartet launch into the opening notes of Pachelbels Canon. At first, all I had to do was bang on the walls with my shovel and a whole mess of them in identical blue gowns and tuxedos would come running out, but I tried that last week and they just kept on chattering like I wasnt even there. Im almost all out of ideas at this point. Contreau later said that he plans to try ringing the barn with barbed wire, which he hoped would snag and slow the movement of anyone in billowy chiffon.
