I read a post about a Bandera vortex Polly’s peak. I live downstream and strongly believe there is a cave system under my land. i was told there was by several people when I brought property and unfortunately had to cover and fill in obvious entrances so no one would accidental fall in them and break legs. I am certain that activity is coming from underground now. I live on a 60 foot solid foot bluff overlooking the horseshoe bend in the Medina River. There are springs coming from underground. There is an incredible water grotto 4 lots away with a 40 foot open cave surround the water grotto. I hear things constantly now underground that sound like slamming doors. Several years ago a vortex came while I was gone and took out two enormous trees and missed my home by 6 inches. This is a very unique piece of property and I am looking for someone to discover the cave system. Especially now that I am hearing constant activity underground. I think I am sitting on a treasure. Who can use equipment to sort of do something like a sonogram…for lack of the proper word before digging blindly? – Cynthia
