It's been a long time since both the Portland Timbers and the Seattle Sounders have competed against each other for the Cascadia Cup, the regional trophy that the Portland Timbers, Seattle Sounders and Vancouver Whitecaps play for each year (more on this later today). This is because the Sounders officially joined MLS in 2009 thus making it impossible for them to compete against either the Timbers or Whitecaps in regular season play.
Of course, one thing that Seattle has been given huge swaths of credit for since joining MLS is their huge fan support (which is respectable). Still, not even as far back as 2007 were the Sounders attendance numbers and supporters group levels fairly small, never really approaching the levels the Portland Timbers were able to muster in the same year.
After the jump I've posted two videos from August of 2007, one of which shows the Emerald City Supporters group at a Sounders game, and another of the Timbers Army. I think the videos speak for themselves...
And before any Seattle fans come running over here to explain the situation: it's all in good fun. Just some good natured ribbing. See you guys on Saturday!
