TRADITION... shitting up state property, the forest, a very ecosystem if you will, seeing that other folks clean up the crap, and doing it over again.
Interesting. I've had a lot of Jersey backwoods traditions that while odd, didn't include such foolishness.
My advice, listen closely from now on. Play down your stance just for a bit. See if you can get a little more detail on who, where, and when. Then, when you think you've got something tangible, pass the information along to authorities. You'll get closer to getting that big smile on your face that Guy speaks of sooner.
Worried about making enemies? I'd use every bit of info in any way from anyone, especially a braggard of the offense and have no problem looking them in the eye to tell them I was the informant. I do not care how close you are to them in the workplace. Ignorance is bliss? Take away some of their bliss.
