It's great news. And a good place to play. Bob is a fantastic owner- caretaker. I'm glad it's selling out consistently and hope that continues for years to come. Maybe one day it will need to be expanded permanently, not just for a Grey Cup.
It isn't really an apples to apples comparison with the early 70s though. At that time, IWS seated 34,000 fans, and was the biggest stadium in the CFL (pre Olympic Stadium in Montreal and expansion of CNE Stadium for the Blue Jays). Average attendance in 1973 was almost 32,000 per game. In 1972 it was over 32,000.
