"I always enjoyed caves, ever since I was a kid," says Dennis Boyer. "Caves are very unique. There are no two caves alike."
Boyer bought the cavern in 1997.
"It was a small tourist attraction that had almost reached the point that they were not operating too much," he says. "After about a year's worth of convincing my wife that this was a good idea we moved here and started restoring the operation."
Boyer turned things around, and now close to 30,000 people visit the cave each year. Now he's improving the underground experience.
"We are doing a major expansion of the cavern," he says. "That's requiring us to remove around 300 tons of rock."
In just a month and a half, crews have almost completed a 110 foot tunnel that will open up to an underground lake.
"We'll then begin putting bridges and walkways in order to take tours much deeper into the cave," Boyer says.
Now, 150 sticks of dynamite later, the crew is just days away from opening the passage.
"This is getting pretty exciting," he says. "We're going to break through. I guess you could kind of call it the light at the end of the tunnel."
