How much of a thrill-seeker are you?
If you find bungee-jumping or white-water rafting a little too scary, you might want to try a new ride in Kentucky.
It's an underground zipline through an old limestone quarry.
Bill Francis was brave enough to do this story and has this report....
"See you all on the backside.....woo hoo!"
Mega zips is open underground at the mega cavern, a huge cave system located under the louisville zoo.
"A lot of people have zipped before but they have never zipped underground."
Now they can.
"One of the most exhilarating and heart pounding experiences that you will ever take."
Zip-lines were once limited to team building programs and exotic tours. But now they're becoming more popular for everyone to enjoy.
"You will be soaring 70 feet above the cavern floor while riding five breathtaking zip-lines."
A zip-line consists of a pulley suspended on a cable and mounted on an incline.
"I've done repelling, I've done parachuting, parasailing, things of that nature and this goes right along with it. I've done some zipping before....this is just awesome."
Mega zips says the experience is a safe one.
"We use the best harnesses, the best gear, and the guides are trained and certified and because of that you feel a complete feeling of safety and security."
Safe enough for even me to give it a try.....
"Before you do a real zip, you get a chance to practice on a bunny zip.....hey that's cool."
Mega cavern co-owner Jim Lowry is transforming the mega cavern into a local tourist attraction.
"And this is just one more reason why that we're going to have that ability to bring more conventions, more tourism into the community."
All of this fun underground where the temperature is always a comfortable 60 degrees.
"Being in the dark it can really mess with people's minds. Which they love it -- it adds to the excitement."
The Mega Zips experience is about two-hours long.
