If it's a Mexican holiday weekend it means their starting a parade and the custom is to pull in behind the cop. If the line of cars hasn't already started you start honking your horn. If no one else gets in line they will stop and let you know where the Fiesta is. Santo Tomas-093.jpg It's also a great way to make new friends. Santo Tomas-096.jpg

Nope -- no Holiday, just a normal day and the cop was just driving along with his lights on, I found it kinda odd.
