Yeah, there was kind of a street party/festival over one block downtown, and we hung around there for a bit, then went further downtown to the store where most of my group had pre-ordered their books to buy them. I, however, opted to buy mine at the 24-hour Shoppers Drug Mart where it was a bit cheaper. (I also bought snacks to fuel my reading marathon!)
There was actually a big party organized at Casa Loma, but I couldn't really afford it. Theoretically, the big HP party for me was Prophecy 2007, though.
