I have a feeling the Heritage Classic in Regina game will sell out without any issues. Part of my reasoning is that there will be a decent amount of fans coming from both Calgary and Winnipeg, given the location of the game. Plus you add fans coming from the Regina region (and Saskatchewan generally speaking), and I think this game will sell out. Let’s say 12K from Winnipeg area, 12K from Calgary area, 12K from Saskatchewan. Not necessarily an exact split like that - might be more from one region than the other, but I don’t think they’ll have any issues packing the building.
Reasons this game will sell out:
1. It's in a hockey-mad, non-NHL city. The citizens of Regina and surrounding areas would sell this out without the help of fans driving in from Manitoba or Alberta. It's a high event game that counts in the standings.
2. There will still be a fair amount of fans driving in from Manitoba and Alberta anyways.
3. Related to point number one... it's in a sports-mad city where there's not much to do outside of Rider season (sorry Regina folks, but it is what it is).
Personally, I find these spectacles much better to watch on television. The site lines at the games are horrible, it's not comfortable whatsoever, and the costs are absolutely outrageous for what you get. Maybe that's why it's in a non-NHL city... fans in Regina would be far less jaded.
