Argos last full season at RC in 2014 had a average of 17,790. They haven't had a 26K average since 2009 which was the last under C & S ownership.

The 2014 figure included comps which have been cut down. Also, the first 2 seasons a BMO, the attendance was based on scanned entry. Not sure if they're doing the same this year
