There were people waiting for a long time in Chapters and other book stores in St. John's... but whoever stayed were the first in North America to get the book since Newfoundland hits 12am before any other part of Canada & the US.
For me... I'm half way (or less) through the fourth book, and that was a few years ago so I forgot practically everything about the series... so I started it again and in about a month I got 20 pages read. Not that much into HP.
