If anyone has ideas for execution, please let me know.
The idea is to create a traffic-clogging throng of "pilgrims" that cripple a Walmart by impeding access to the store and the parking lot.

Some see Virgin Mary in underpass stain
CHICAGO, Illinois (AP) -- A steady stream of the faithful and the curious, many carrying flowers and candles, have flocked to an expressway underpass for a view of a yellow and white stain on a concrete wall that some believe is an image of the Virgin Mary.
Police have patrolled the emergency turnoff area under the Kennedy Expressway since Monday as hundreds of people have walked down to see the image and the growing memorial of flowers and candles that surround it. Beside the image is an artist's rendering of the Virgin Mary embracing Pope John Paul II in a pose some see echoed in the stain.

Tuesday morning, women knelt with rosary beads behind a police barricade while men in work shirts stood solemnly before the image, praying. A police officer kept the crowd of about three dozen from getting too close to the traffic but didn't stop them gathering around the stain.

Among the best-known in the United States was an image seen in office windows in Clearwater, Florida. Within weeks, a half million people had been to the site. Glass experts believe the image was created by a chemical reaction and corrosion of the metallic elements in the glass coating, but they could not explain why it took the shape it did. The windows were broken last year.
