If you show up today, on this utterly miserable rainy, 40 degree and dropping, north winds at 20 mph, in a nightmare season against a non rival foe, you ARE a die-hard Michigan fan. If you don't make it (unless you are on your deathbed, or moving away, or out of town, or at your kids soccer game), die-hard status DENIED. These are the types of games that define a die-hard fan.
Oh and since it's now at 40 degrees or below, the no hard liquor in the stadium rule has been waived.
Likewise if you're a crafter and you're not at the Detroit Urban Craft Fair today, you're just dabbling.
