May 8th, Seattle Center

The VGC (Video Game Championship) qualifier is taking place on May 8th at the Seattle Center - I'll probably skip playing this year, but the www.pokemonvgc.com website does mention "You'll find plenty of
opportunities to face off against other Pokémon Trainers, plus you'll have
the chance to receive a special Shiny Pokémon!"

I'm hoping that means I don't have to play to get the Eevee. I'll probably pack a team just in case though.
