VIDEO: Copa90 goes inside what they call "most incredible fan culture in the US" | SIDELINE

Following a recent trip to Seattle for the second leg of the Seattle Sounders' Western Conference semifinals matchup against FC Dallas, soccer supporters culture advocates Copa90 have called their findings (above video) the "most incredible fan culture in the US."

The Copa90 website describes itself as follows: "At Copa90 we know there is no final whistle. Pitch, laptop, or console, the game never stops. … We think it is the stories outside the 90 minutes where the true heart of football is found."

OK, so they might know a little something about supporters culture. With credentials now established, they bestowed the crown of "most incredible fan culture in the US" upon the city of Seattle.

There are plenty of MLS cities Copa90 is still yet to visit, but if you take the time to watch their above video report — which is incredibly done — are they right?
