sadly such a critter probably does,
when Man battles God and the Nature He created, we lose.
Just turn into an extension of the existing tourist cave.
They are at least ten miles apart, and this cave is in the middle of a subdivision, hence the need to fill it in. I live in the county in question, and there was extensive exploration of the karst topography, and we have greenbelts where there are potential sinkholes. I think this is an older development that did not undertake such exploration.
