In Michigan you must inform if carrying. And the back of our card carries a list of places that you can not frequent while carrying. Blood Alcohol tolerance is very low .02 and you are in trouble.
The back reads and I quote
"This license allows the licensee to carry a pistol on or about his person anywhere in the state, except a licensee shall not carry a concealed pistol at a school, on school property, day care center, child placing agency, sports arena, Stadium, bar or tavern licensed to serve liquor, church, synagogue, mosque, temple or other place of worship, entertainment facility seating more than 2500 people, hospital, dormitory or classroom of a college or university or casino or as otherwise prohibited by law. Consult the statue for complete wording of pistol free zones."
These zones are know here as criminal empowerment zones here.
A few of these have been relaxed a little over the years but not very much or nearly enough.
