my wife and I went to see the sounders play San Jose when we were there in may. She didn't think she'd have fun but she didn't sit once and sung and cheered the whole time. Great crowd and atmosphere - I highly recommend checking it out. Also about an hour before the game the fans meet at a park about ten blocks away and have a rally and then march all together, it was lot of fun. Drew Carey is the owner and as there to lead the rally. Make sure you buy a sounders shirt or something too - it's an awful green but you'll stick out like sore thumb without one
