Discussions

I remember someone posting something about the semi trailer parked in the Shopper's Mall parking lot, that had all those Question Marks all over it, and there was speculation over what it meant. I can't seem to find that discussion (not really sure how to use the search option, especially since I can't remember what the discussion was titled). Can anyone please help me out, if that has been answered, what it was for? I'd really appreciate it. Thanks
