Bet they will have zoning laws soon in MI
City of Dearborn passed Ordinance 11-1316 earlier this year... stated CG's can apply & license in commercially zoned areas, and that this would be run through the Chief of Police. This was back in March... as of last week, the Police Dept still denies this even exists... at least the two times I called to inquire about... funny, think they are in denial.
And Ann Arbor finally got through with passing regulations...
