TBH I’ve found the MCG atmosphere to be overrated. You’re pretty far from the other side of the crowd, and it doesn’t have the same noise containers that a place like Suncorp (or even Eden Park) have. The MCC members are also the most pompous, silent gronks found at Australian sporting venues.
I’ve been to two grand finals and two all Victorian prelims there too. And while the atmosphere was good, they ain’t got shit on the Broncos 2015 prelim at suncorp, any origin game three at suncorp or an all Sydney NRL GF at Homebush.
