Oh I went to the one the day before! Is it really coming up to ten years already...
It was incredibly fun, there was such a good atmosphere. Likewise on it being a very cherished memory. I've been to many, many conventions before with tons of Pokémon fans, but it felt really different being at the concert for some reason, seeing so many Pokémon fans in one place made me really emotional. And of course, the music was played fantastically.
