No trespassing
It almost feels like they’re asking this not for our sake, but for their sake. If you enter this restricted area, these people aren’t worried about your safety, they’re worried about all the work they’d have to deal with. We don’t know who put up this ominous sign, but it’s enough to keep us out of these woods.

There are a lot of ways to deal with unwanted intruders, and while usually these “no trespassing” signs are rather useless, we think this one would do the trick. We wouldn’t take our chances here, because it seems as if those people aren’t playing any games. Although the sign is pretty funny.
