Getting to the parade

[Rickomatic]

As one unfamiliar with the intricacies of the regions mass transit system, can anyone shed some light on getting into Seattle tomorrow via transit? Particularly from Snohomish County. The Sound Transit site has next to zero info. I did see a Tacoma News Tribune article stating that the south end Sounder train is scheduled to Seattle for tomorrow's parade. I saw nothing in regards to the North end route.
Can anyone help a fellow 12 out as to the best way/train/bus route to either downtown or The Clink?

Edit: from either Everett/Lynnwood/Edmonds area or North Seattle
