My daughter and I took a trip to the Louisville, Kentucky area for spring break 2013. One of the local attractions we decided to explore were the Mega Caverns and wow, what an adventure we had! Neither of us had ever been zip lining before but were up for something new. After the inital preparations, away we went on 6 different lines and all of them were underground. Our guides were David & Molly who were extremely skilled and able to answer any questions we had. It was an awesome experience and I recommend it to everyone.
