The Lechusa's Of Falfurrias, Texas

In a small town of falfurrias, texas there are things called Lechusa's. They are to be half woman and half bat. In order to call them out you have to tie 7 knots in a rope, for every knot you have to say a prayer. If you are that brave you have to untie the knots and say the prayers backwards. Legend has it that if you make a mistake in the process of calling them out or making them go way they will kill you, if they have not already kiiled you. Late at night you van hear them scratching on neighbor roof tops. I guss there is only one Question for the other people that live in falfurrias, texas... are any of them brave enough.
