You can also buy tickets directly from season ticket holders using the ticket exchange system. Try
this site, or just go to ticketmaster.ca where you'll be able to see all seats, whether available from the venue or from resale.
Also, prior to the Labour Day game, a lot of Bomber fans like to congregate in some guy's backyard next to the west side of the stadium. This has been going on for some years now. It's a party for everyone involved! Not sure where those Bomber fans will go next year though. You guys will need to start a new tradition.
