Playing at Qwest Field
67,000 is maximum capacity
32,400 is how many tickets they have sold for their home opener - which is 48% of stadium capacity
The game has been declared a sell out!
27,700 will be the capacity for games the rest of the first season - which is 41% of stadium capacity

And don't even get me started on them playing on fake turf - no matter how good Sigi says it is, it's still fake turf
