You cannot wear a mask in public to conceal your identity.

The Law Explained

Enacted in the mid-20th century, this law was originally passed to combat the Ku Klux Klan and prevent members from hiding their faces during rallies. The statute makes it a misdemeanor to wear a mask, hood, or device that conceals one's identity. Exceptions are made for Halloween, theatrical productions, and, more recently, medical emergencies.
