I did the midnight thing for the fifth one. I went to Borders with two of my friends, and we won a stupid trivia game, which let me have a free copy of the book, but I had already preordered it, and they wouldn't give me any credit for it, so I have 2 copies of the fifth book, plus a Harry Potter hat (it's in my closet somewhere), and some other usesless junk. I got there at 10, and left at 12:01 (winners get first in line priviledges, and there were ~100 people there). It was so boring. I wasn't going to do anything this time, but after reading this thread, I've decided to go to Wordsworth in Harvard Sq. (Cambridge) right now, and see if it's any better there.
