I would have seen that Son of a ^%&#! in court.Sadly in Illinois the laws are a gray area, left up to the individual officer interpretation of said law. One officer may be fine with what you are doing, and the next officer will write you a ticket.
Mid-afternoon on a rural unpaved road, pulled off the road just watching a herd of 30 whitetail deer 300 yards away. No Fireams in the truck. Illinois DNR pulls up and wrote me a ticket for harassing wildlife!
