Both your assumptions are false.
I drove through east lansing once and ate at an applebees or a fridays, I can't remember, but it was one of those 2.
And I have been a Michigan fan all of my life. My father grew up as a Michigan fan in Detroit. He then raised me a Michigan fan, and trust me, a fair weather fan would not hang a 4x6 flag above their bed and drive 10 hours to Michigan from NJ to see a college football game.
I don't know what causes you to think that I am a fair weather fan, but I am not.
I'm sorry then. Do you live in Michigan, cause if you do you will know what I am talking about. State fans get so much s*** for wearing the green and white. Even at the Okemos Mall (closest mall a mile or so from campus) has so much U of M stuff. I see alot of people, some even students here, who wear U of M stuff. It isn't hard being a fan of a top program, and yes Michigan is a top program. Come basketball it is way different (for obvious reasons), but there is a real hatred for much of U of M here. The fab five f***ed with State too, by sitting down on the S on our basketball court. You don't see me walking on the golden M.
