[Dan from Michigan]

If you have a CCW issued after July 1, or an old general CCW, you can carry anywhere in the state outside of the special gun free zones which are specifically mentioned in the law.(Schools, bars, places that serve alchohol, sports arenas.)

[Demidog]

Schools, bars, places that serve alchohol, sports arenas.

In other words you are forbidden from carrying them where you need them the most.
