After the first two games of the season (both at home) saw Blue Bomber fans stack their empty watered-down Molson cups up rows and rows of seats, the team had to respond.
Unfortunately, the Winnipeg Football Club continues to face new challenges with respect to unruly and/or disorderly behavior in the stadium facility during the course of game day. Specifically, this behavior relates to the “beer snake” concept. Regretfully, we witnessed the beer cups being thrown at the conclusion of our home game of July 9th which resulted in several minor injuries to our fans as well as many emails and communications to our office voicing concern and displeasure from our fans.
There's probably good reason to ban it. According to the CBC article, the beer snake spanned 30 rows. I'm not a mathemagician, but if we conservatively estimate that a row of seats is a yard long (we're not accounting for incline or the curve of the cups) and it's about five cups to an inch of beer snake, then we're looking at a minimum 5400 cups located in one super-drunk area of the stadium to be used as ammunition when your team loses at home to Toronto.
