bouteloa:Years ago, I put nails in a board and hid it nail end up in the tall grass. It was pretty evident that some trespassers had a bad day driving on that.
Bad ideaianr33:If you are worried about safety you could just blast the entrance shut.Would not be the first time!!
Publicly name the idiot, post a no trespassing sign (this way the idiots that dont know what land ownership means will be informed they are not to be there, pretty stupid requirement IMHO), and install a grate that is maintainable that will not allow law abiding individuals in and not allow criminal trespassers out. After all there is a room in there and its probably a good place to sit the off season pondering if it was all worth it. Its a shame for what it sounds like your trying to do there someone would do this knowing it'll probably lead to more restrictive access versus less. Hope the local community there helps you in this, while you do have access to the resource for them, that access can just as quickly be taken away. Good luckbouteloa:...Yesterday I was informed that a cave diver had announced that he had bypassed the usual cave route by entering the spring entrance to the cave and swam through until it opened up into a room....
plot:Some type of an underwater gate could stop them I'd think. When you really think about it, it wouldn't have to be much of a gate. A diver can't get through an arrea smaller than what? 2' by 2'? So fabricate some type of metal barred gate taking that into consideration with wide openings. There'd be more than enough room for debree and whatever else to get through, just not humans.
Depending on how big the opening is, weld a bunch of fence posts togethor with 2'x2' gaps (maybe slightly smaller or larger depending on what everyone else thinks).
