I see. And I see this has been defended in a case against Ferndale.
How odd it is then, that both Ann Arbor & Saline have local ordinances, apparently in violation of state law (I discovered after posting this). I feel comfortable their prohibitions are unenforcable, after reading the decision in the Ferndale case, but it disturbs me that they would pass ordinances which knowingly violate state law.
There should be criminal penalties for lawmakers who take part in such shenanigans, in my opinion. It's dishonest and clutters up the legislature with confusing and meaningless laws.
Anyhow, thanks for answering my question! o
