It should come as no surprise that trying dangerous things can lead to some pretty unfortunate consequences. Still, some like to play with fire.
A group of instructors certainly did when they decided to test out a new zipline in Florida. The line itself gave no cause for alarm, as it was very sturdy and stable. The real (and terrifying) problem is that it passed directly over an alligator-infested pond.
One woman in particular got quite a scare when she took a ride down the line.
