They announced this event way too late and I had plans for the afternoon, otherwise I would have gone. It's very rare that there are official Pokemon events here in Canada.

Events period are a rarity, let alone in Canada. I was obviously going to go to the NYC Toys R Us or PokeCenter but that didn't work out, lol. Maybe for Ranger or TCG.
