Yeah. We had a similar situation here in Va till we finally got complete preemption. OC was never illegal, but various cities banned it. And there was no perfect list of which ones.
Thankfully we have VCDL. So that problem went away. A few cities acted like dorks and tried to push the issue. They were visited en masse by VCDL during their council meetings and had amazing policy conversions. A few others got cute and arrested folks for OC. They got the ever popular visit plus a lawsuit.
See my last post above.
