Okay so my one plot I'm very sure is not going to be found but anyways there is only one enterance and hard to get through and I wanted to get a bear trap so if someone walked in it would snatch them, but apparetly they are illegal and i cant buy those lol. I want to set up a trap that will tell me if someone has found or going to my one plot. I was thinking of setting up some type of trip-wire, but an animal could trip that also. But then I thought Maybe put up barbed wire very tight in a fence like way, so that an animal wouldnt get past, unless its short and small enough. Then after that put the trip wire that would be tripped and drop something to alert me or soemthing that would hit or attack the person, in a way that wont seriously hurt them but warn them, that goes there so I know the person was there and they know I know they were there So yeah my idea was a barbed wire type fence low enough that someone could step over if they want to, but a small animal like a groundhog could get past, but would stop a larger animal. and then a trip wire after that is a little higher that the smaller animal could get by without tripping it, but a person would trip it. So the barbed fence would stop a big animal from getting to the trip wire, and a small animal wouldnt trip it, so I would know it was a human being that tripped it. Sounds like a good idea right? If so, how can i make such a trip wire? What do I need and how do i do it? Also, what else can I do to know if a person was there? What other traps? Im not looking to spend hundreds on a camera to put out there.
