The ones you saw when you travelled are called bandwagon fans. They pop up when teams get good. They’re not real. And I don’t accept them.
Ive lived on the west coast of Canada and the US for 43 years. Have met maybe 10 actual Bills fans other than me. Rarely saw any paraphernalia for sale.
In the past 2 years I see Bills stuff everywhere.
Dont be fooled. Get yourself a quiz made up. If these people don’t know who Jake Arians is, they can move along.
