And guess what! There has to be a sign posted stating such!
If there is no sign, then that cop trying to catch smokers is like a hunter shining a light on a deer at night.
PUT UP A SIGN!
Then smokers can know ahead of time before they lay down their blankets and gear. What's fair is fair. Not to be blind sided by some cop.
You have a point. I've also heard the point made saying "ignorance of the law is no excuse."
