Park City, Kentucky - As promised, here are more photos from this morning's zip-line tour. As you can see, these ladies of the Women's Outdoor Adventure were truly walking on air as they zipped across five lines in Mammoth Cave National Park. Thanks to our guides at Mammoth Cave Adventures for keeping everyone "zipping on!"

The fun times didn't stop there - we'll have more photos of our adventures, including horseback riding and more time on the range coming up tomorrow.
