I want to go see the King Awesome bobblehead night game versus the Nationals in early June.  I've never been to a bobblehead night before, so I have a couple questions.

1)  How fast do tickets sell for those games.  I prefer sitting in the CF area (lower deck).

2)  How early is it advised to get to the game so I can get one of those bobbleheads?

The Mariners and the Nats are my two favorite teams, so this would be a great opportunity for me to see a game.
