I was sent this in an email at work, and wished I was in New York City to take some snapshots of this at night:
...Some of Manhattan's other HP7 weekend plans, including a Borders event Friday night, where "the front of the Time Warner Center will be bathed in orange light, and the lobby in front of the Borders bookstore at the center will be draped in curtains and decorated with ice sculptures. . . . [Shortly before midnight, a horse and carriage will pull up outside the building on Columbus Circle. The carriage will bear the object of all this marketing magic--a copy of Harry Potter and the Deathly Hallows."
Too cool. There may be similar scenes (though probably not as extravagant) at other large cities around the world during release dates.
