Perfect superman form.

Sometimes the zipline organizers change things around a little. This is called face-first ziplining, or "superman mode"--can you guess why?

First you have to take your harness off and put it on backwards. Then, when it's your turn you stand in the "launch area" and they hook up a shoulder harness, and your "turned-around" regular harness, on your back.

As you approach the edge of the cliff, there is NOTHING in front of you. No rappell rigging, nothing to hold on to, just a deep gorge in front of you. You just have to run straight ahead and jump off the cliff, against all your instincts.

As you travel out on the zip line, you look down on all the trees, and all the rocks, and the river below. This time, you don't rappel down, but rather your fellow zipliners pull you back. As you come back and approach the edge of the gorge, you might have to grab a root or tree branch to get yourself oriented, and finally you'll be back on your feet again.
