SARATOGA, Minn. – A spirited political activist posted a yard sign inviting motorists to honk if they supported his candidate. A neighbor didn’t like noise and called the sheriff. A deputy drove out to the bucolic and normally tranquil 28000 block of Highway 74. The partisan claimed his sign was constitutionally protected as free speech. The deputy pointed to the neighbor’s righto peace and quiet. The resolution: Signs yes, honking no.
