Welcome back.
My journey is the opposite. I lived in WNY as a youngster before I really knew what Football was and before the Kelly era. Moved to Detroit and in MI it is ALL about college ball. I was casual fan (of the Lions more than the Bills which were dominating), also had lived in Maryland and had just really started to get back into Football when the Ravens won the SB.
By that time I was back living in WNY and watching football.
I became a Bills fan during the Rob Johnson Era.
I remember listening to the radio when games were blacked out.
I moved out of the area and HAD to get the ticket to watch the Bills plan. I suffered through the Jauron era, the 2008 collapse and watched everyone of last years losses. I am still in complete shock.
It doesn't matter how you came back, just that you did :-)
