Took me 20 packs (sorry, I didn't bust a box, so I didn't record the box break), but I got 'em. I've opened 23 packs in total, 5 this morning after my 18 on Wednesday.
Now, to finish off the base set (I'm about halfway; anyone else bust this stuff and have doubles?). The cards are pretty good, more or less Score-quality base cards, not a ton of inserts in the packs I opened, and I got Antawn Jamison and Ishmael Smith autos in the first half a box I opened.
On the flipside, how cool must it be to be one of these people in the crowd?
