Despite having lower attendance numbers than previous years, I think Edmonton still has one of the highest attendance records in the league (size of venue might help in this regard, somewhat).
I'm curious to see what the atmosphere will be like with the upper bowl closed off. With everyone spread out, the atmosphere can fall off a cliff. Seattle Sounders MLS soccer team used to close the upper bowl, as they shared the stadium with Seahawks. When the lower bowl was full, and upper bowl closed, the sounders games were rocking.
