You're bringing (IMO) the variable of illegal activity into the equation where it doesn't belong. I stated in the original post that everything being done was being done,legally.
But to do something legally, it has to be definable.
And to add to the mess, you may have common sense GW's where you live, but here in PA, they used to fine guys coming out of the woods after dark for hunting after hours. Our times ended at sunset. Even if you chose to honor the law and quit hunting with full light, sometimes a long hike out or even being pinned down by deer and making you late would get you a fine. They've since changed the rules thankfully.
