It was years later when Randy was on a picnic luncheon date, that he found another sink hole. He went home to get his caving gear and asked Gary Tenen to join him to explore the new sink hole. That new sink hole was also disappointing, but Randy and Gary decided upon a whim to return to the prior sink hole. This time they could smell bat guano, a hint that the cave might be much larger than they had originally thought. It was after crawling about the length of a football field, sometimes on their bellies, with only carbide lamps for light, that they came to a very small bat hole. After chipping away at the hole for hours they entered the "Big Room". While there, they realized that this discovery could place the caverns at risk.
