Well..... Since you asked:
-Rewatch the 84, 88, 90, 19 and 21 GCs
-Wear some kind of Bombers gear every day of GC week
-Read every piece of content you can find online about the team this week
-Soak up all the attention on the team because the offseason is brutally long
-Pray, in a sort of ironic way...
-Make sure you have plenty of beer from Manitoba breweries
-Make sure you have plenty of whiskey made in Manitoba (both Crown Royal and "New Make")
-Let the wife get her appie-making on....
-On gameday, start drinking at breakfast
-CJOB pregame from start to finish
Let's. *******. Go.
