I had 20 acres many years ago that got dumped on, not that a sign would have prevented this. Rogue contractors looking to dump their garbage to avoid paying a dump fee. This was before tree cams were available.
Ya, wonderful, "live free or die" NH contractors?
I guess the live free means dump your crap where ever as long as you don't get caught.
If all you have to worry about is hunters then you're good.
