Man......I just wore by Team OR-EE-GON hat a few days ago, too.....
There's really nothing I can say that others here have not said already. Cason was one of the few people I knew who could play a fantastic, skilled game of Pokemon (both the TCG and GBA games) while still being completely cool and friendly to anyone who talked to him. He wouldn't even insult people in a joking manner, he was just nice to everyone.
While I really never did anything with him outside of the Pokemon tourneys, I (and all of us in Team Salem, actually) knew him and respected both his attitude and his abilities. It was literally impossible to not like the guy.
My prayers are with Matt and Jan. May God help you through this time.
Sincerely,
Marvin
PS. Cason.dec FTW.
