You cannot string a rope across a public highway.

The Law

In the days of horse-drawn carriages and early, open-top automobiles, stringing a rope or wire across a road was a malicious prank that could easily decapitate a rider. This law was enacted specifically to criminalize these deadly traps. Though the prank has long since fallen out of style, the law remains as a testament to dark historical humor. It is a severe felony meant to deter dangerous highway sabotage.
