One word: Whee.
For those unfamiliar with Zipline, take warning, it is not for the faint of heart.
It consists of two raised platforms connected by a long cable from which hang harnesses that people strap themselves into.
Then they fling themselves off into space and gravity does the rest, whipping the joyriders at heart-stopping speeds along the track to the bottom platform.
Greene County bigwigs are hoping the zipline tour, scheduled to open this summer, will give local tourism a hefty boost.
