It is a traffic offense to scare horses or stampede livestock.
Hmm, I don’t think I will be stampeding any livestock in San Francisco. That is something I would be more concerned about in Cairo.
And, for those of you who are curious, I have to read the verdammte drivers handbook because California makes out-of-staters take the written driving exam. I shouldn’t complain too much. International drivers also have to retake both the written AND the driving exam.
