I noticed a few months ago that a newly installed beach-rules sign in Miami specified no weapons, contrary to state law. I’ve seen signs like this before. Until recently local officials faced no costs for promulgating local rules that violated Florida’s preemption law.
I happened to pass that sign a few days ago and the weapons line had been whited out.
It is progress. It takes a long time, sometimes. Tea Party sympathizers should keep this in mind.
